[PMID: 38613196 DOI: 10.1002/ohn.757] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 02/21/2024] [Accepted: 03/15/2024] [Indexed: 04/14/2024]
Abstract
OBJECTIVE To investigate the survival benefit of elective neck dissection (END) over neck observation in surgically resected cT1-4 N0M0 head and neck basaloid carcinoma (HNBC). STUDY DESIGN Retrospective cohort study. SETTING The 2006 to 2017 hospital-based National Cancer Database. METHODS Patients with surgically resected cT1-4 N0M0 HNBC were selected. Linear, binary logistic, Kaplan-Meier, and Cox proportional hazards regression models were implemented. RESULTS Of 857 patients satisfying inclusion criteria, the majority were male (77.0%) and white (88.1%) with disease of the oral cavity (21.5%) or oropharynx (42.9%) classified as high grade (76.9%) and cT1-2 (72.9%). 389 (45.4%) patients underwent END. END utilization between 2006 and 2017 increased for cT1-2 disease (33.3% vs 56.9%, R2 = .699) but remained relatively constant for cT3-4 disease (66.7% vs 57.9%, R2 = .062). One-hundred and fifteen (29.6%) ENDs detected occult nodal metastases (ONMs). The 5-year overall survival (OS) of patients undergoing neck observation and END was 65.6% and 66.8%, respectively (P = .652). END was not associated with improved OS in survival analyses stratified by patient demographics, clinicopathologic features, and adjuvant therapy. Compared with surgery alone, adjuvant radiotherapy (adjusted hazard ratio: 0.74, 95% confidence interval [CI]: 0.57-0.97, P = .031) was associated with improved OS. END (hazard ratio [HR]: 0.96, 95% CI: 0.71-1.28, P = .770) and ONM (HR: 1.12, 95% CI: 0.78-1.61, P = .551) were not associated with OS. CONCLUSION END is performed in nearly half of patients with HNBC but is not associated with improved OS, even after stratifying survival analyses by patient demographics, clinicopathologic features, and adjuvant therapy. The rate of ONM approaching 30%, however, justifies inclusion of END in the surgical management of HNBC.

Abstract
BACKGROUND This paper reports the first case of basaloid squamous cell carcinoma clinically and radiologically masquerading as a head and neck paraganglioma. CASE PRESENTATION A 66-year-old Sinhalese male with unilateral hearing impairment and 7th-12th (excluding 11th) cranial nerve palsies was diagnosed radiologically with a head and neck paraganglioma by magnetic resonance imaging of the brain, which revealed a hypointense and hyperintense punctate mass centered at the jugular fossa with intracranial extension. The ascending pharyngeal artery, recognized as the major feeder, was embolized by percutaneous embolization following digital subtraction angiography. Gross total resection of the tumor was followed by an uneventful postoperative recovery. Combined immunohistochemistry and histopathological morphology revealed a basaloid squamous cell carcinoma, following which the patient completed radiotherapy and is at 3-month follow-up currently. CONCLUSION This case report discusses the diagnostic pitfalls and management challenges of this rare entity on the basis of prior evidence, as well as a literature review and clinical and surgical analysis.

Abstract
In this case report, we address a rare entity of parotid cancer: basaloid squamous cell carcinoma, which was surgically unresectable and had thus far only been treated with radiation therapy. Following twenty years of continuous remission, our patient presented with an acute perimesencephalic subarachnoid hemorrhage. The cause of the acute perimesencephalic subarachnoid hemorrhage was a delayed complication of radiation therapy.

Abstract
ABSTRACT Basaloid squamous cell carcinoma (BSCC) is a distinct, high-grade variant of oral squamous cell carcinoma (OSCC) with a poor prognosis. In the head and neck region, the most common sites are the epiglottis, piriform sinus, and tongue base. Other less common sites include the floor of the mouth, oral mucosa, palate, tonsils, nasopharynx, and trachea. In the present report, the unusual case of a 69-year-old male is presented; the patient exhibited ulceroproliferative growth involving the lower alveolus. Incisional biopsy was done and the hematoxylin and eosin-stained sections revealed tumor islands with dysplastic oral epithelial cells invading the underlying connective tissue as islands, cords, and nests. The presence of palisading basaloid cells with a central area of comedo necrosis and keratin formation on the islands revealed the diagnosis of BSCC. Immunohistochemistry demonstrated positive staining for proliferative cell nuclear antigen (PCNA) and pan-cytokeratin. The patient is still under treatment and follow-up.

Abstract
The upper aerodigestive tract is where basaloid squamous cell carcinoma (BSCC), a rare variation of conventional SCC, is most frequently found. The hypopharynx, tonsil, supraglottic larynx, tongue (base), and head-neck regions are particularly susceptible to BSCC. Clinically, the presentation of BSCC is similar to that of conventional SCC, but it has a poorer prognosis than conventional SCC. BSCC is distinguished histopathologically by a dimorphic pattern, a distinctive basal cell component paired with a squamous component, and a squamous component. However, its similar features to conventional SCC make it difficult to diagnose. Therefore, histopathology and immunohistochemistry play a crucial role in diagnosing such tumors. Here we present the case of a 70-year-old male diagnosed with BSCC involving the tongue.

Abstract
INTRODUCTION AND IMPORTANCE Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive subtype of squamous cell carcinoma. BSCC in the larynx is an extremely rare occurrence, with only a few cases reported in the medical literature. This case report aims to shed light on the clinical presentation, diagnostic challenges, histopathological features, and therapeutic considerations associated with this rare entity. CASE PRESENTATION This case report describes a 65-year-old male patient who presented with hoarseness and dyspnea. Laryngoscopy revealed a 2.5 cm pedunculated lesion on the left vocal cord. The patient underwent a laryngectomy, and the histopathological examination of the excised specimen confirmed the diagnosis of BSCC. CLINICAL DISCUSSION BSCC of the larynx is a rare malignancy comprising less than 1 % of laryngeal cancers. Clinical features often overlap those of squamous cell carcinoma, such as hoarseness, progressive breathing difficulties, and swallowing issues. Treatment approaches vary, with some opting for neo-adjuvant radiotherapy before surgery, like in this case, while others favor surgical excision as the primary treatment, supplemented by adjuvant chemo- or radiotherapy in certain cases. CONCLUSION Basaloid squamous cell carcinoma is a rare variant of squamous cell carcinoma. Clinicians and pathologists should be aware of the distinctive characteristics of BSCC and its potential clinical aggressiveness. While rare, early recognition and appropriate management are essential for achieving favorable outcomes in patients with this challenging condition.

Tumor-Stroma Ratio in Basaloid and Conventional Laryngeal Squamous Cell Carcinoma: Prognostic Significance and Concordance in Paired Biopsies and Surgical Samples. Cancers (Basel) 2023; 15:cancers15061645.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a subtype of squamous cell carcinoma (SCC) associated with a poor prognosis. Tumor–stroma ratio (TSR) has been introduced as a prognostic feature in many solid tumors. TSR was investigated in a series of laryngeal BSCCs and compared with a group of stage-matched conventional SCCs (cSCCs), in both preoperative and surgical specimens, with the intent of ascertaining the more aggressive behavior of BSCC and verifying the presence of stromal-related causes. A series of 14 consecutive laryngeal BSCCs and a control group of 28 stage-matched conventional cSCCs were analyzed. A higher nodal metastasis presence was found in BSCCs (57.1% vs. 28.6%). The recurrence rate was 33.5% and 63.6% in the cSCC and BSCC groups; disease-free survival (DFS) was higher, though not significantly, in patients with cSCC. TSR, large cell nests, and tumor budding showed a moderate to very good agreement, and stroma type a good to very good agreement between biopsies and surgical specimens in the cSCC group. In the BSCC group, agreement was poor to very good for TSR and stroma type, and good to very good for large cell nests and tumor budding. Age was the only feature significant in predicting recurrence in the BSCC group (p = 0.0235). In cSCC, TSR low/stroma rich cases, when evaluated on biopsies or surgical specimens, were associated with lower DFS (p = 0.0036; p = 0.0041, respectively). Laryngeal BSCCs showed a lower DFS than cSCCs, even if statistical significance was not reached. TSR, evaluated in laryngeal biopsies and excised tumors, was prognostic in terms of DFS in cSCC but not in BSCC cases.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive subtype of squamous cell carcinoma (SCC). To date, no consensus on the treatment of BSCC has been established yet, especially in cases of invasion of the skull base. In addition, long-term prognosis has not been reported in T4b cases. Herein, we report the case of a 36-year-old Japanese man with locally advanced nasal BSCC that directly invaded the skull base and the brain. The patient was then treated with induction chemotherapy (IC). Owing to his good response to IC, we planned and performed en bloc resection followed by adjuvant proton beam therapy (PBT). Follow-up examinations five years after treatment showed no evidence of recurrence. This is the first report of IC followed by radical surgery and adjuvant PBT in a patient with T4b. IC has the potential to play an important role in treatment strategies.

Abstract
Esophageal basaloid squamous cell carcinoma (bSCC) is a subtype of squamous cell carcinoma (SCC) with a different behavior and poor prognosis. Exploring bSCC's molecular characteristics and treatment strategies are of great clinical significance. We performed multi-omics analysis of paired bSCC and common SCC (cSCC) using whole exome sequencing and a NanoString nCounter gene expression panel. Immunohistochemistry was used for verification of candidate biomarkers. Different treatment response was analyzed on both patients receiving neoadjuvant treatment and late-stage patients. The common genetically-clonal origin of bSCC and cSCC was confirmed. No significant differences between their genetic alterations or mutation spectra were observed. Mutation signature 15 (associated with defective DNA damage repair) was less prominent, and tumor mutational burden (TMB) was lower in bSCC. bSCC with an RNA expression pattern resembling cSCC had a better survival than other bSCCs. Moreover, bSCC showed significant upregulation of expression of genes associated with angiogenesis response, basement membranes, and epithelial-mesenchymal transition, and downregulation of KRT14 (squamous differentiation) and CCL21 (associated with immune response). Immunohistochemistry for SFRP1 was shown to be highly sensitive and specific for bSCC diagnosis (p < 0.001). In addition, bSCC receiving neoadjuvant immuno-chemotherapy had a worse pathological response than bSCC receiving neoadjuvant chemotherapy (but without statistical significance), even in bSCC positive for PD-L1. Our results demonstrated the molecular characteristics of esophageal bSCC as a subtype with a distinct RNA expression pattern and immune characteristics, but no specific genetic mutations. We provided a useful biomarker, SFRP1, for diagnosis. After outcome analysis for six bSCCs with neoadjuvant immunotherapy treatment and four late-stage bSCCs with immunotherapy, we found that immunotherapy may not be an effective treatment option for most bSCCs. This may also provide a clue for the same subtypes of lung and head and neck cancer. Our study highlighted the heterogeneity among bSCC patients, and might explain the conflicting results of bSCC outcomes in existing studies. © 2022 The Pathological Society of Great Britain and Ireland.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a rare, distinctive, and aggressive variant of squamous cell carcinoma (SCC) primarily seen in the upper aerodigestive tract with epiglottis, soft palate, and base of the tongue being site of high preference in head and neck region. It differs from conventional SCC histologically and immunologically, is most frequently found in males in their sixth and seventh decades, and is frequently linked to alcohol and tobacco use. High stage disease with distant metastases, a high recurrence rate, and a dismal prognosis is how BSCC typically manifests. In the present article, we report four cases of BSCC.

[PMID: 36588005 DOI: 10.1016/j.ejso.2022.12.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 11/17/2022] [Accepted: 12/24/2022] [Indexed: 12/27/2022] Open
Abstract
INTRODUCTION Recently, the number of diagnosed esophageal basaloid squamous cell carcinoma (EBSCC) has gradually increased. However, available data on EBSCC are limited to date. METHODS A total of 165 EBSCC (Cohort 1) and 515 conventional esophageal squamous cell carcinoma (ESCC) (Cohort 2) were retrospectively analyzed. RESULTS In Cohort 1, 70 cases only had invasive EBSCC component (42.4%, defined as Group 1), 73 cases had concomitant invasive ESCC component (44.2%, Group 2), and 22 had concomitant invasive poor-differentiated component (13.3%, Group 3). Lymph node metastasis rates of Group 3, Group 2 and Group 1 were ranked from high to low (P = 0.044). There were higher patient age (P = 0.047), smaller tumor size (P = 0.009), more nerve invasion (P < 0.001), and lower pTNM stage (P < 0.001) in EBSCC (Cohort 1), compared with ESCC (Cohort 2). In Cohort 1 and Cohort 2, pTNM stage was an independent prognostic factor for both DFS and OS. No significant survival difference was found between EBSCC (Cohort 1) and ESCC (Cohort 2) in pIA-B stage, pIIA-B stage, pIIIA-B stage and pIVA-B stage (P > 0.05). CONCLUSION Our analysis of the largest EBSCC series from a single institution to date with conventional ESCC demonstrated that EBSCC carried a similar prognosis with ESCC in pIA-B stage, pIIA-B stage, pIIIA-B stage and pIVA-B stage. And pure EBSCC, didn't have poorer survival than mixed EBSCC with concomitant ESCC or other components. Our findings may be valuable in the better understanding of EBSCC's biological behaviors, and the related molecular mechanism is needed to be explored in the future.

Abstract
OBJECTIVE The purpose of this study was to analyze the difference of survival rates in paitents with oropharyngeal keratinizing squamous cell carcinoma (KSCC), nonkeratinizing squamous cell carcinoma (NKSCC), basaloid squamous cell carcinoma (BSCC), and papillary squamous cell carcinoma (PSCC). MATERIALS AND METHODS Patients diagnosed with oropharyngeal squamous cell carcinoma between 2004 and 2015 were collected from the SEER database. Cox proportional hazards models and Kaplan-Meier curves were used for survival analysis. Propensity score matching (PSM) was performed to adjust for the effect of confounding variables. Due to the small sample size of PSCC, this study did not perform PSM between it and other subtypes. RESULTS The 5-year cancer-specific survival (CSS) rate of PSCC was higher than that of KSCC, NKSCC, and BSCC (0.627 vs. 0.812 vs. 0.789 vs. 0.875, P < 0.05); And the CSS rate of KSCC was lower than that of other subtypes both before and after PSM. In addition, the 5-year and 10-year CSS rates of BSCC were not different from NKSCC (P > 0.05), but not as good as NKSCC in the long term (P = 0.028). After PSM, the 5-year, 10-year, and long-term prognosis of BSCC were significantly worse than those of NKSCC (P < 0.001). CONCLUSION The 5-year CSS of PSCC was better than the other three subtypes. The short-term prognosis of BSCC was not significantly different from NKSCC, but the long-term survival was lower than that of NKSCC, and the difference was more obvious after PSM. Meanwhile, the prognosis of KSCC was worst.

Esophageal squamous cell carcinoma with basaloid features are genetically and prognostically similar to conventional squamous cell carcinoma. Mod Pathol 2022; 35:1247-1253. [PMID: 35351978 DOI: 10.1038/s41379-022-01060-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Revised: 02/18/2022] [Accepted: 02/18/2022] [Indexed: 11/08/2022]
Abstract
We compared clinicopathologic and molecular features of esophageal squamous cell carcinoma (SCC) with basaloid features to conventional SCC using surgical resections of treatment naïve esophageal carcinomas and cases available from the TCGA database. Twenty-two cases of SCC with basaloid features were identified in the Mass General Brigham pathology archives, including 9 cases with pure basaloid morphology and 13 cases with mixed other features such as conventional well- or poorly differentiated areas or sarcomatoid areas. Thirty-eight cases of conventional SCC matched by tumor stage were used as controls. HPV infection status was tested by p16 immunohistochemistry and HPV mRNA ISH. Digital slides for 94 cases of esophageal SCC from TCGA found in the Genomic Data Commons (GDC) Data Portal were reviewed. Five cases of SCC with basaloid features were identified. Genomic profiles of SCC with basaloid features were compared to the rest of 89 SCCs without basaloid features. In addition, eight tumor sections from six patients selected from our cohort underwent in-house molecular profiling. Compared to conventional SCC, SCC with basaloid features were more frequently associated with diffuse or multifocal squamous dysplasia (p < 0.001). P16 IHC was positive in 2/13 cases, whereas HPV mRNA ISH was negative in 17/17 cases (including both p16-positive cases). SCC with basaloid features and conventional SCC from TCGA showed similar rates of TP53 mutations, CDKN2A/B deletions, and CCDN1 amplifications. TP53 variants were identified in all in-house samples that had sufficient coverage. Survival analyses between SCC with basaloid features versus conventional SCC (matched for tumor stage) did not reveal any statistically significant differences. In conclusion, esophageal SCC with basaloid features has similar survival and genomic alterations to those of conventional SCC, are more frequently associated with diffuse or multifocal dysplasia, and are not associated with HPV (high-risk strains) infection.

Abstract
Phototherapy, including photothermal therapy (PTT) and photodynamic therapy (PDT) has attracted growing attention as a noninvasive option for cancer treatment. At present, researchers have developed various “all-in-one” nanoplatforms for cancer imaging and PTT/PDT combinational therapy. However, the complex structure, tedious preparation procedures, overuse of extra carriers and severe side effects hinder their biomedical applications. In this work, we reported a nanoplatform (designated as ICG-MB) self-assembly from two different FDA-approved dyes of indocyanine green (ICG) and methylene blue (MB) without any additional excipients for cancer fluorescence imaging and combinational PTT/PDT. ICG-MB was found to exhibit good dispersion in the aqueous phase and improve the photostability and cellular uptake of free ICG and MB, thus exhibiting enhanced photothermal conversion and singlet oxygen (1O2) generation abilities to robustly ablate cancer cells under 808 nm and 670 nm laser irradiation. After intravenous injection, ICG-MB effectively accumulated at tumor sites with a near-infrared (NIR) fluorescence signal, which helped to delineate the targeted area for NIR laser-triggered phototoxicity. As a consequence, ICG-MB displayed a combinational PTT/PDT effect to potently inhibit tumor growth without causing any system toxicities in vivo. In conclusion, this minimalist, effective and biocompatible nanotheranostic would provide a promising candidate for cancer phototherapy based on current available dyes in clinic.

Abstract
OBJECTIVE To investigate the clinicopathologic features and prognostic factors in oral basaloid squamous cell carcinoma. METHODS Retrospective analysis of oral basaloid squamous cell carcinomas patients who underwent tumor resection during the period from January 2002 to December 2020 in the authors' hospital, especially the clinicopathologic characteristics of 28 cases with confirmed diagnosis and follow-up data. Immunohistochemistry was performed to define the helpful markers for differentiation diagnosis. The factors influencing the prognosis were evaluated based on Kaplan-Meier method. RESULTS The tongue and mouth floor (11 cases, 39.3%) were the most frequently involved sites, followed by gingiva (6 cases, 21.4%), buccal (5 cases, 17.9%), palate (4 cases, 14.3%), and oropharynx (2 cases, 7.1%). The majority of basaloid squamous cell carcinomas were in advanced stage, with 12 cases in stage Ⅱ and 16 cases in stages Ⅲ-Ⅳ. Twelve of 28 patients were identified to have cervical lymph node metastasis, which was confirmed by histopathological examination. The incidence rate of lymph node metastasis was 42.9% (12/28). Nine tumors recurred, with one metastasized to the lung. At the meantime, the 28 conventional squamous cell carcinomas were matched with the same stage, among which 13 cases were identified with cervical lymph node metastasis. The incidence rate of lymph node metastasis was 46.4% (13/28). Five cases recurred, with two cases that metastasized to the lung and one to the brain. The 5-year overall survival rates of the basaloid squamous cell carcinoma and conventional squamous cell carcinoma patients were 54.6% and 53.8%, respectively. Histopathologically, basaloid cells consisted of tumor islands without evident keratinization but frequently with comedo-like necrosis within the tumor islands. CK5/6 and P63 exhibited strongly positive in all the 28 cases, whereas neuroendocrine markers, CgA and Syn, were negative. Eight cases positively expressed P16; one case showed focal SOX10 positive but CK7 negative. CONCLUSION The majority of oral basaloid squamous cell carcinomas present in advanced stage with a high tendency to lymph node metastasis, but the overall survival rates are not significantly different from conventional squamous cell carcinomas matched with the same stage. The human papilloma virus (HPV), as HPV-positivity rate is high, correlates to good prognosis. In addition, CK7 & SOX10 immunohistochemistry could contribute to differential diagnosis for basaloid squamous cell carcinoma with solid adenoid cystic carcinoma.

Abstract
A 71-year-old man presented to our otolaryngology clinic with dysphagia and dyspnoea. He had a history of smoking for 40 years. Laryngoscopy showed an exophytic, round mass on the left aryepiglottic fold that was entirely excised by transoral laser CO2 microsurgery. Histological assessment revealed a pT1 basaloid squamous cell carcinoma (BSCC) with free-margin resection. He underwent close follow-up and after 3-year follow-up, the patient was free from disease. Laryngeal BSCC is a rare cancer with poor prognosis due to its late diagnosis and early neck node metastases. We report a rare case of early tumour treated by endoscopic surgery without complications or recurrence of disease. However, knowing this type of cancer and making a correct differential diagnosis are important to guarantee the best therapy and prognosis.

Abstract
Background Esophageal basaloid squamous cell carcinoma (EBSCC) is a rare malignancy. Serum apolipoprotein A-I (APO A-I) has proved to be a potentially useful prognostic indicator in various cancers. However, no studies have analyzed the prognostic significance of serum APO A-I in patients with EBSCC. The aim of this study was to investigate the prognostic impact of preoperative serum APO A-I in patients with EBSCC. Methods Between 2007 and 2018, a retrospective study of 4050 patients with resectable esophageal squamous cell carcinoma (ESCC) including the levels of preoperative serum lipids was conducted and evaluated. The best cut-off values of the preoperative serum lipids were evaluated by receiver operating characteristic (ROC) curves. Kaplan–Meier analyses and Cox regression analyses were analyzed the overall survival (OS) and recurrence-free survival (RFS). A prediction model of nomogram was developed to predict individual OS and RFS in EBSCC. Results There were 53 patients enrolled in the study, which accounted for 1.31% (53/4050) of all primary ESCC. The best cut-off point was 1.305 g/L for serum APO A-I according to the ROC curve. Patients with lower levels of serum preoperative APO A-I were associated with worse RFS (16.1% vs 54.5%, P = 0.006) and OS (29.0% vs 63.6%, P = 0.010). The results indicated that serum APO A-I serves as an independent predictor in patients with EBSCC regarding OS [hazard ratio (HR): 0.352; 95% confidence interval (CI): 0.154–0.808; P = 0.014] and RFS (HR: 0.397; 95% CI: 0.185–0.850; P = 0.017). Conclusion Preoperative serum APO A-I is an independent predictor regarding OS and RFS in EBSCC. As far as we know, this is the first study in EBSCC to explore the serum APO A-I in patients with EBSCC.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a rare, unique, and aggressive variant of squamous cell carcinoma which mostly occurs in the upper aerodigestive tract. Histologically and immunologically different from conventional squamous cell carcinoma, it is mostly seen in men of the sixth and seventh decades and is commonly associated with tobacco and alcohol usage. BSCC usually presents as a high stage disease with distant metastasis, high recurrence rate, and poor prognosis. In the head-and-neck region, BSCC has a strong predilection for sites such as the base of the tongue, soft palate, and epiglottis. Less commonly, it may also occur on the floor of the mouth, gingiva, and tonsils. In the present article, we report a case of BSCC in the right maxillary anterior gingiva of a 57-year-old female for its rarity.

Abstract
PURPOSE Basaloid squamous cell carcinoma (BSCC) is a rare aggressive variant of squamous cell carcinoma (SCC) with a poor prognosis. No large series of exclusively hypopharyngeal BSCC patients have been previously reported. Therefore, this retrospective population-based study aims to explain the patient demographics, clinicopathologic characteristics, incidence, and survival outcomes of hypopharyngeal BSCC and how it relates to conventional-type SCC. METHODS The National Cancer Institute's Surveillance, Epidemiology, and End Results database registry was queried for patients diagnosed with hypopharyngeal BSCC and conventional-type SCC between 2001 and 2016. RESULTS The incidence of hypopharyngeal BSCC from 2001 to 2016 was 0.0161 per 100,000 individuals. The BSCC group comprised 213 patients, and the SCC group 7958 patients. The majority of BSCCs were considered high grade (Grade III/IV, 89.58%). Most BSCC patients were diagnosed at an advanced stage (American Joint Committee on Cancer [AJCC] stage IV, 65.38%). The 1-, 5-, and 10-year disease-specific survival (DSS) rates for hypopharyngeal BSCC were 84.10%, 57.40%, and 46.20%, respectively. Multivariate analysis, after adjustment for sex, age, race, tumor location, grade, and AJCC stage, showed that patients with BSCC had significantly better DSS than those with conventional-type SCC. Surgery with radiation contributed to a favorable DSS for BSCC patients in comparison with other treatments. CONCLUSION This analysis of the largest hypopharyngeal BSCC series indicates a better prognosis for this pathologic type compared with conventional-type hypopharyngeal SCC. Multimodality treatment with surgery and radiation may result in a favorable prognosis for hypopharyngeal BSCC patients.

Constitutive Hedgehog/GLI2 signaling drives extracutaneous basaloid squamous cell carcinoma development and bone remodeling. Carcinogenesis 2021; 42:1100-1109. [PMID: 34117865 DOI: 10.1093/carcin/bgab050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Revised: 05/17/2021] [Accepted: 06/09/2021] [Indexed: 11/14/2022] Open
Abstract
Uncontrolled activation of the Hedgehog (Hh) signaling pathway, operating through GLI transcription factors, plays a central role in the pathogenesis of cutaneous basal cell carcinoma and contributes to the development of several malignancies arising in extracutaneous sites. We now report that K5-tTA;tetO-Gli2 bitransgenic mice develop distinctive epithelial tumors within their jaws. These tumors consist of large masses of highly proliferative, monomorphous, basaloid cells with scattered foci of keratinization and central necrosis, mimicking human basaloid squamous cell carcinoma (BSCC), an aggressive upper aerodigestive tract tumor. Like human BSCC, these tumors express epidermal basal keratins, and differentiation-specific keratins within squamous foci. Mouse BSCCs express high levels of Gli2 and Hh target genes, including Gli1 and Ptch1, which we show are also upregulated in a subset of human BSCCs. Mouse BSCCs appear to arise from distinct epithelial sites, including the gingival junctional epithelium and epithelial rests of Malassez, a proposed stem cell compartment. Although Gli2 transgene expression is restricted to epithelial cells, we also detect striking alterations in bone adjacent to BSCCs, with activated osteoblasts, osteoclasts, and osteal macrophages, indicative of active bone remodeling. Gli2 transgene inactivation resulted in rapid BSCC regression and reversal of the bone remodeling phenotype. This first-reported mouse model of BSCC supports the concept that uncontrolled Hh signaling plays a central role in the pathogenesis of a subset of human BSCCs, points to Hh/GLI2 signaling as a potential therapeutic target, and provides a powerful new tool for probing the mechanistic underpinnings of tumor-associated bone remodeling.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a poorly differentiated variant of squamous cell carcinoma (SCC) with distinct morphologic characteristics. Yet, there are no clearly defined guidelines established for management. BSCC in the esophagus is a very rare entity, with the proportion of esophageal BSCC ranging from 0.068% to 11%. This wide range is thought to be secondary to difficulty making the diagnosis on small biopsy specimens and the lack of a universally defined proportion of BSCC components necessary to make the diagnosis. We present the case of a 57-year-old African American female, who underwent esophagogastroduodenoscopy (EGD) after an abnormal barium swallow in the setting of two months history of dysphagia and weight loss and was diagnosed with BSCC of the esophagus on histopathology.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a rare variant of squamous cell carcinoma characterized by a conglomerate of clinically aggressive course and disparate histopathological features. It is frequently seen in upper aerodigestive tract area. Histopathologically, it is biphasic and composed of two types of tumor cells, namely basaloid and squamous cells. Tumor markers, namely, BerEp4, epithelial membrane antigen and p53 are used in this case to differentiate from similar tumors which impersonate BSCC histologically but differ prognostically. We report a case of BSCC in a 48-year-old female patient, involving the lateral border of the tongue with an exhaustive picture of its histological and immunohistochemical appearance.

Abstract
Mutations in the tumor suppressor CYLD, known to be causative of cylindromas, were recently described in a subset of high-risk (hr) HPV-positive head and neck squamous cell carcinomas (HNSCC). Pathologic and genetic characterization of these CYLD-mutant carcinomas, however, remains limited. Here, we investigated whether CYLD mutations characterize a histopathologically and genomically distinct subset of hrHPV-positive HNSCC. Comprehensive genomic profiling via hybrid capture-based DNA sequencing was performed on 703 consecutive head and neck carcinomas with hrHPV sequences, identifying 148 unique cases (21%) harboring CYLD mutations. Clinical data, pathology reports, and histopathology were reviewed. CYLD mutations included homozygous deletions (n = 61/148; 41%), truncations (n = 52; 35%), missense (n = 26; 18%) and splice-site (n = 9; 6%) mutations, and in-frame deletion (n = 1; 1%). Among hrHPV-positive HNSCC, the CYLD-mutant cohort showed substantially lower tumor mutational burden than CYLD-wildtype cases (n = 555) (median 2.6 vs. 4.4 mut/Mb, p < 0.00001) and less frequent alterations in PIK3CA (11% vs. 34%, p < 0.0001), KMT2D (1% vs. 16%, p < 0.0001), and FBXW7 (3% vs. 11%, p = 0.0018). Male predominance (94% vs. 87%), median age (58 vs. 60 years), and detection of HPV16 (95% vs. 89%) were similar. On available histopathology, 70% of CYLD-mutant HNSCC (98/141 cases) contained hyalinized material, consistent with basement membrane inclusions, within crowded aggregates of tumor cells. Only 7% of CYLD-wildtype cases demonstrated this distinctive pattern (p < 0.0001). Histopathologic patterns of CYLD-mutant HNSCC lacking basement membrane inclusions included nonkeratinizing (n = 22, 16%), predominantly nonkeratinizing (nonkeratinizing SCC with focal maturation; n = 10, 7%), and keratinizing (n = 11, 8%) patterns. The latter two groups showed significantly higher frequency of PTEN alterations compared with other CYLD-mutant cases (38% [8/21] vs. 7% [8/120], p = 0.0004). Within our cohort of hrHPV-positive HNSCCs, CYLD mutations were frequent (21%) and demonstrated distinctive clinical, histopathologic, and genomic features that may inform future study of prognosis and treatment.

Abstract
The literature date estimated that about 5% of all oral cavity cancers are hard palate cancers while soft palate cancers account for about 5-12% of oropharyngeal cancers. Although rare, usually these tumors had a more aggressively behavior than other oral cancer sites. That is why our study aimed to investigate comparatively the epidemiological, clinical and histopathological peculiarities of the two palatal sites of oral squamous cell carcinomas. We conducted a retrospective study limited to a period of 10 years in a single medical institution to investigate the morphoclinical profile of such tumors. We found that patients with hard palate SCCs had an average age slightly larger compared to those who developed soft palate tumors. Also, those with hard palate tumors are mostly diagnosed in less advanced stages compared to those at the level of the soft palate, and implicitly the former had a longer survival time. Histopathologically the most encountered hard palate SCC were the conventional well-differentiated tumor, and from the peculiar SCC variant the papillary and verrucous forms while for the soft palate SCC prevailed the moderate and poor differentiated conventional SCC and from the peculiar SCC variant the basaloid and acantholytic forms. In conclusion hard palate tumors differ in many aspects from those of the soft palate, and thus specification of the origin tumor site become important for the assessment of prognosis, treatment and survival outcome of such patients.

Abstract
OBJECTIVES Rare diseases are often poorly understood, and this study sought to investigate the incidence of a rare disease entity, basaloid squamous cell carcinoma (BSCC) of the oral cavity (OC) at a tertiary care medical center and to assess its clinical outcomes. METHODS The aim of this study was to collect data in order to better understand how this rare disease progresses. This was a case series of patients with OC BSCC diagnosed between 2001 and 2018. RESULTS 10 patients with primary OC BSCC were identified. Average age at diagnosis was 58 years (33-71). The median follow-up period was 11 months. Primary sites included oral tongue (n = 4), floor of mouth (n = 4), hard palate (n = 1), and retromolar trigone (n = 1). A majority (60%) of patients had pathologic T3/T4 tumors. All patients underwent primary surgical treatment. There was an overall 60% mortality rate: 2 died from metastasis at 1- and 3-months postop, 2 from unknown causes, 1 from sepsis at 1 month postop, and 1 from metastatic colon cancer. Average survival for those patients who died was 20.7 months. 4 patients were disease-free at the time of publication. CONCLUSION There are few studies in the literature that seek to investigate cases of OC BSCC from a single institution. This is the first detailed case series of BSCC from a single American institution. Survival outcomes in our cohort were poor but demonstrate a variable course of disease burden. This study presents unique information regarding specific pathologic characteristics and patient outcomes for this rare disease.

Abstract
In a retrospective review, we identified 332 patients with 338 pathologically diagnosed primary oropharyngeal carcinomas (OPC) between January 2013 and March 2020 with known p16/HPV status from a tumor registry at Northwestern Memorial Hospital. The tumors predominantly involved the palatine tonsil (51 %) and the base of the tongue/lingual tonsil (38 %). The most common type of cancer was non-keratinizing squamous cell carcinoma (60 %), and the majority of primaries were p16 positive/HPV-mediated (86 %). A cohort of p16 positive/HPV mediated OPC (27/283, 9.5 %) presented with aggressive clinical behavior, including multiple distant metastases at unusual sites. Tumor size >2 cm and the presence of tumor anaplasia/multinucleation were significantly associated with an increased rate of distant metastases in p16 positive/HPV mediated cases, both in unadjusted and adjusted analyses (all P < 0.05). Of the 332 individuals in the overall cohort, 38 individuals died due to their disease within the observed follow-up time. Among the 283 patients with p16 positive/HPV mediated tumors, survival was estimated at 97 % (95 % CI 95 %, 100 %) at 1 year, 95 % (95 % CI 92 %, 98 %) at 2 years, and 80 % (95 % CI 72 %, 89 %) at 5 years. The presence of tumor anaplasia/multinucleation and distant metastasis were both significantly associated with poorer disease-specific survival in p16 positive/HPV mediated cases (both P < 0.05), with the survival effect of tumor anaplasia/multinucleation likely mediated in part through its association with distant metastasis. For p16 positive/HPV-mediated OPC, age, smoking status, tumor status, and lymph node status were not significantly associated with disease-specific survival in our study.

Abstract
Basal cell carcinoma (BCC) of the skin is the most common type of malignant human tumor. In Europe, the incidence of BCC ranges from 44.6 to 128 cases per 100,000 inhabitants annually, whereas in the United States, the yearly incidence rate ranges between 500 and 1500. The global incidence has been calculated to be as high as 10 million cases of BCC per year. There are 2 main clinical patterns of BCC-the familial BCC in basal cell nevus syndrome and sporadic BCC. The etiology of cutaneous BCC is usually the result of the interaction between solar ultraviolet radiation and genetic factors. Somatic or germline mutations in the effector components of the hedgehog signaling pathway (ie, PTCH1, PTCH2, SMO or SUFU genes) are responsible for ∼90% of the cases of both sporadic and familial BCC, all causing a constitutive activation of the hedgehog pathway. Cutaneous BCC very rarely metastasizes, and diagnosis in metastatic sites can be very difficult. Metastatic BCC has weakly effective therapeutic options with a poor prognosis until few years ago. In 2012, small-molecule therapies, involving inactivation of the hedgehog signaling pathway, and capable of reducing tumor growth and progression have been introduced into clinical practice for advanced (locally advanced or metastatic) BCC. We performed a comprehensive literature review on metastatic BCC and found at least 915 cases reported to date. In addition, we extensively discussed the differential diagnosis of metastatic BCC, and outlined the advances in clinical therapeutics involving these small molecules.

Abstract
BACKGROUND Compared with colorectal adenocarcinoma, basaloid squamous cell carcinomas (BSCCs) arising in the colorectum are rare and have very poor prognosis. To date, only nine cases have been reported. Most BSCCs are extensively involved in metastasis to the lymph node, liver, and lung at diagnosis. Despite many clinicians attempting to effectively treat BSCCs, therapeutic consensus has not been established due to lack of information.
CASE SUMMARY A 58-year-old woman presented with abdominal pain, diarrhea, fever, and hematochezia. She was referred from a department of gynecology and was diagnosed with a suspicious leiomyosarcoma of the rectum or a pedunculated myoma of the uterus. An exophytic growing mass at the right lateral wall of the rectum with an internal cystic portion and hemorrhage was observed on magnetic resonance imaging. The patient underwent low anterior resection and total hysterectomy with bilateral salphingo-oophorectomy. Histopathological findings revealed a cellular mass with a solid growth pattern and few glandular structures, many foci of intratumoral necrosis, and a palisading pattern. The pathologist diagnosed tumor as a BSCC, and the patient received chemotherapy with fluorouracil/leucovorin without radiotherapy. The patient is currently alive 8 years after the surgery with no manifestations of metastatic colon cancer.
CONCLUSION Our case suggest that curative resection and chemotherapy play important roles in improving survival, and radiotherapy may be an option to avoid radiation-associated enteritis.

Abstract
As an aggressive subtype of squamous cell carcinoma, basaloid squamous cell carcinoma (BSCC) rarely occurs in the oral and maxillofacial region. The gingiva is an unusual site of BSCC. This study reported a 78-year-old male who presented with left maxillary pain. Clinical examination revealed a gingival mass in the left maxilla. Under microscope, the lesion showed typical comedo necrosis and peripheral palisading. Areas of glandular-like structures were also observed. Immunohistochemistry results revealed that the Ki-67 score of BSCC in this case was 28%, and S-100 was positive in some areas. However, P16 and CK7 were negative. Finally, a diagnosis of BSCC was made based on the pathological and immunohistochemical characteristics. The patient underwent subtotal maxillectomy. After 12 months later, the patient was alive with no evidence of disease. Combined with relevant literature, this article analyzed the clinicopathological features, differential diagnosis, diagnosis, treatment, and prognosis of BSCC. Although surgery remains the main treatment in the head and neck region, radiation-chemotherapy should be considered in some human papilloma virus-positive cases.

The importance of adjuvant treatment and primary anatomical site in head and neck basaloid squamous cell carcinoma survival: an analysis of the National Cancer Database. Clin Transl Oncol 2020; 22:2264-2274. [PMID: 32440914 DOI: 10.1007/s12094-020-02370-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2019] [Accepted: 05/01/2020] [Indexed: 10/24/2022]
Abstract
PURPOSE Basaloid squamous cell carcinoma (BSCC) of the head and neck is an aggressive and highly malignant variant of squamous cell carcinoma that accounts for 2% of head and neck cancers. Previous studies have not analyzed the significance of adjuvant chemoradiation and anatomical site within BSCC subtype and its impact on survival. METHODS A cohort of 1999 patients with BSCC of the head and neck was formed from the National Cancer Database and analyzed with descriptive studies, median survival and 5- and 10-year survival. A multivariable Cox hazard regression was performed to determine the prognostic significance of anatomical site and adjuvant therapy. RESULTS The most common primary anatomical site was the oropharynx (71.9%) followed by oral cavity (11.5%), larynx (10.1%), hypopharynx (3.5%), esophagus (1.9%), and nasopharynx (1.1%). The presence of metastasis increased the risk of mortality (HR = 2.14; 95% CI 1.40-3.26). Tumors localized to the oropharynx demonstrated better survival compared to all sites except nasopharynx, including the oral cavity (HR = 2.45; 95% CI 1.83-3.29), hypopharynx (HR = 2.58; 95% CI:1.64-4.05), and larynx (HR = 2.89; 95% CI:2.25-3.73). Adjuvant chemoradiation (HR = 0.36; 95% CI 0.23-0.58) and adjuvant radiation (HR = 0.38; 95% CI 0.23-0.64) had better survival outcomes compared to adjuvant chemotherapy. Patients with microscopic margins had better survival outcomes when compared to no surgery (HR = 0.38, 98% Cl 0.23-0.64) while there were no better survival outcomes of patients with macroscopic margins compared to no surgery. CONCLUSION This study illustrated that tumors in the oropharynx, lower age, adjuvant chemoradiation and radiation, and microscopic margins were associated with greater survival.

Abstract
Sinonasal inverted papilloma (IP) is a benign, locally aggressive epithelial neoplasm. In less than 9% of cases it is associated with malignancies, typically conventional squamous cell carcinomas (SCC), while other histological variants have been less frequently reported. We describe the third case of basaloid squamous cell carcinoma (BSCC) arising in nasal IP. An 81-year-old female patient presented with a pinkish irregular lesion on the nasal septum. Biopsy was consistent with IP and carcinoma in situ. Two surgical procedures were needed to obtain radical excision. Histology on the surgical specimen revealed BSCC. Seven months after surgery, there was no evidence of disease recurrence. Although IP is more frequently associated with conventional SCC, other malignancies should be considered. The histological differential diagnosis should be supported by immunohistochemistry. The generally-recommended treatment for sinonasal BSCC is complete surgical resection, although this may be a problem in multifocal distributions, as in the present case.

Abstract
Basal cell carcinoma (BCC) of the skin is the most common type of malignant human tumor. However, metastatic BCC is a very rare event with weakly effective therapeutic options and a poor prognosis, until a few years ago. In 2012, small-molecule therapies, capable of inactivating the hedgehog signaling pathway and thus reducing tumor growth and progression, were introduced into clinical practice for the treatment of patients with advanced BCC. We present retrospectively 2 personal cases of metastatic BCC of the skin, from the premolecular therapy era, from primary tumors that arose years before in the head and neck area. The former case occurred in a 45-year-old woman with a history of recurrent BCC of the retroauricular skin who eventually died due to diffuse metastatic spread. The latter case concerned a 70-year-old man also with a history of recurrent BCC of the nasal-perinasal skin who developed multiple subcutaneous and lymph node metastases in the neck. In both cases, the diagnoses were based on biopsies of the metastatic sites. The first patient died 5 months after the diagnosis of metastatic disease, while the second was alive and disease-free 2 years after neck lymph node dissection and external radiation therapy, and then lost to follow-up. We extensively discuss several tumor entities with basal or basaloid features that may enter the differential diagnosis with BCC in metastatic sites. In addition, we briefly summarize the advances in clinical therapeutics using small molecules, which are now an integral part of the treatment of such advanced BCC cases.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a subtype of squamous cell carcinoma that characteristically occurs in the head and neck, may be related to HPV infection and is usually considered to be aggressive. We present the first description of BSCC of the breast. The tumor exhibited characteristic histologic features of BSCC, including nests of basaloid squamous cells with comedonecrosis, abrupt keratinization, and abundant hyaline basement membrane-like material deposition. The tumor showed immunohistochemical features of triple negativity, diffuse p63 positivity, p16 positivity, and Rb negativity. HPV immunogenotyping was negative. The patient was free of disease after treatment with breast conserving surgery, chemotherapy and radiotherapy. BSCC of the breast should be distinguished from basaloid adenoid cystic carcinoma, triple-negative basal-like breast cancer and nonbasaloid squamous cell carcinoma of the breast based on histology and immunohistochemistry. The prognostic implications of BSCC of the breast should be further studied in larger series.

Abstract
PURPOSE The aim of this study was to analyze the clinical features of BSCC in the oral cavity, diagnosed over 31 years of service in oral pathology, and make comparisons with the data reported in the literature. METHODS Data regarding gender, age, clinical presentation, anatomical location, symptoms, evolution time, size of lesion, and use of alcohol and tobacco from cases of BSCC were collected. Additionally, we conducted a review of BSCC studies from searches in three electronic databases. RESULTS Among 24,570 oral biopsies, 7 (0.03%) were BSCC and represented 0.8% of oral squamous cell carcinoma (n = 875). All cases occurred in males, and the prevalent affected age was the sixth decade (60%). Ulcers occurred in all cases, with the majority showing no symptoms (71.4%). The tongue (30.8%), alveolar ridge/gingiva (30.8%), and floor of the mouth (23.1%) were the anatomical locations affected. The literature review indicated a total of fifteen publications, reporting 214 cases of BSCC. Males (76.7%) in the seventh (53.3%) decade of life were most affected. According to the cases with adequate information, symptomatic (90.0%) ulcers (80.0%) in the floor of the mouth (42.1%), with a mean size of 2 cm and the mean evolution time of 1.5 to 18 months were the most seen. Association with tobacco and alcohol use, when noted, was 50.0%. CONCLUSION The features presented in this study are more similar than different when compared with the literature data.

Abstract
This study evaluates the prognostic impact of several factors in oropharyngeal squamous cell carcinoma (OPSCC), controlling for human papillomavirus (HPV)-associated tumors and stage (American Joint Committee on Cancer 8th edition). All patients in Southern California Permanente Medical Group diagnosed with OPSCC between 2006 and 2012 tested for p16 immunohistochemistry were included. Review of all pathology materials was combined with central p16 testing. Multivariable analyses were performed. The cohort of 390 patients included 342 p16-positive and 48 p16-negative tumors. For all-comers, on univariate analysis, the following factors, when present, were associated with improved patient survival: p16-positive tumor (n = 324, p < 0.001); crypt versus surface tumor location (n = 312, p = 0.004); nonkeratinizing type (n = 309, p < 0.0001); nonkeratinizing with maturation type (n = 37, p < 0.0001); basaloid pattern (n = 284, p = 0.005); and a broad, pushing border of infiltration (n = 282, p = 0.004). Inferior survival outcomes were observed with: age ≥ 55 years (p < 0.0001); ≥ 10 pack-year smoking history (n = 183, p = 0.003); increasing tumor stage (p < 0.0001); overt radiographic extranodal extension (ORENE) (n = 58, p < 0.0001); low level IV/Vb lymph node involvement (n = 45, p = 0.0002); a jagged pattern of infiltration (n = 76, p = 0.0004); tumor ulceration (n = 76, p = 0.0004); absent lymphocytic infiltrate (p < 0.0001); and concurrent dysplasia (n = 125, p = 0.009). On multivariable analysis, accounting for patient age, smoking history ≥ 10 pack-years, and TNM stage, for patients with p16-positive disease, advanced TNM stage (p = 0.007), the presence of ORENE (p = 0.0002), and low-neck lymphadenopathy (p = 0.0001) were independent negative prognostic factors for disease free survival (DFS). Older age (p < 0.0001), smoking history ≥ 10 pack-years (p = 0.02), advanced TNM stage (p = 0.0002), ORENE (p = 0.004), and low-neck lymphadenopathy (p = 0.002) were independent negative prognostic factors for OS. Among patients with p16-positive OPSCC, older age, smoking history, advanced stage, ORENE, and low-neck lymphadenopathy were significant negative prognostic factors for DFS and/or OS. Further refinement of staging to incorporate additional lymph node findings may be warranted.

Abstract
We aimed to immunohistochemically characterize the pattern of expression of epithelial markers in rare head and neck squamous cell carcinoma (HNSCC) variants: carcinoma cuniculatum (CC) and adenosquamous carcinoma (ASC). We also present an additional variant of HNSCC with concomitant basaloid and squamous components that has overlapping morphological features with odontogenic and non-odontogenic tumors, which we termed basalo-squamous carcinoma (BSC). The selected markers included CK5/6, p40, CK19, BerEP4, p16 and SOX10. All tumors were CK5/6 and p40 positive. CK19 and BerEP4 were positive in BSC and focally in ASC but negative in CC. p16 was positive in 3 (60%) of the CCs, focally positive in ASC and negative in BSC. SOX10 was negative in all three variants. Our results highlight the plasticity of the lining epithelium revealing differential profiles of immuno-expression of the selected molecular markers, possibly reflecting their diverse histopathogenesis.

Abstract
Background Basaloid squamous cell carcinoma (BSCC) is a rare subtype of squamous cell carcinoma with a high rate of distant metastasis. BSCC occurs most commonly in the esophagus, lungs, and head and neck. However, BSCC occurring in an atypical site without a known primary tumor and/or with the presence of atypical immunohistochemical features can result in delayed diagnosis or misdiagnosis. Case presentation Here, we report a case of a 67-year-old man with liver metastatic BSCC with negative pancytokeratin (AE1/AE3) expression. He presented with a chief complaint of epigastric discomfort. Imaging examination revealed a subcapsular mass in the right anterior lobe of the liver. Then, the patient underwent an irregular right hepatectomy. Grossly, the mass was gray, with a size of 7 × 7 × 4 cm. Microscopically, the mass comprised epithelioid tumor cells with both solid and pseudoadenoid structures, accompanied by necrosis. Immunohistochemical staining showed that the tumor cells were negative for AE1/AE3, CK18, CK7, CK19, Hepatocyte Paraffin-1, Glypican-3, Arginase-1, CD56, Chromogranin A, Synaptophysin, Vimentin, and Carcinoembryonic antigen. The Ki-67 index was 80%.The mass was diagnosed as a malignant tumor but could not be classified further. One month after surgery, the patient’s reexamination revealed esophageal tumor, and biopsy revealed BSCC. The slides of the liver tumor were reviewed, and the morphology was similar to that of the esophageal tumor. Moreover, supplementary immunohistochemical staining of liver tumor indicated p63 and p40 were strongly positive, that confirmed the liver tumor was metastatic BSCC. Previous studies have reported that 3.7% of esophageal BSCCs did not express AE1/AE3. Conclusion When a malignant tumor comprises epithelioid cells with solid and/or pseudoadenoid structures, but not adenocarcinoma or neuroendocrine carcinoma, even if the tumor cells are negative or weakly positive for AE1/AE3, we should consider BSCC. For a definite diagnosis, immunohistochemical staining for squamous cell carcinoma markers, including p63 and p40, and examination of common primary sites of BSCC should be performed.

Abstract
CONTEXT Beyond squamous carcinoma, a variety of diagnostically challenging neoplasms arise within various head and neck sites. This is particularly the situation with neoplasms where little cellular cytoplasm is present to assist the pathologist in categorizing such lesions. OBJECTIVE To highlight diagnostic pitfalls that accompanying neoplasms composed primarily of 'cytoplasmically-poor' cells. These pitfalls include morphologic and immunohistochemical traps that emerge from this class of neoplasms. DATA SOURCES Selection of pathologic specimens from the author's personal files, and literature review. CONCLUSIONS Interpretative pitfalls regarding the histopathology and immunophenotype of small 'cytoplasmically-poor' neoplasms are a diagnostic hazard in head and neck surgical pathology practice, and require knowledge of histomorphologic plasticity and aberrant immunophenotyping.

Abstract
Basaloid squamous cell carcinomas (BSCCs) in oral lesions are extremely rare, and the histology is not well understood. Histologically, they are often similar to conventional squamous cell carcinoma (SCC). The present study was designed with an aim to distinguish BSCC from SCC using claudin‑4, occludin, SRY‑box 2 (SOX2) and proliferating cell nuclear antigen (PCNA) immunoreactivities and staining patterns. Three BSCCs (with abundant, with moderate, and without squamous components) specimens and 20 SCC specimens were selected for comparison of their immunoreactivity. These specimens were stained with claudin‑4, occludin, SOX2 and PCNA. In addition to histological analysis, the expression of claudin‑4, occludin and PCNA was determined in oral cancer HSC2 and HSC3 cells with or without SOX2 overexpression, and cell proliferation was determined by XTT assay. Claudin‑4 had strong and occludin had weak immunoreactivity as detected in the membrane of squamous components of BSCC but not in cancer cells. No obvious detection of squamous components and cancer cells were observed in SCC. SOX2 and PCNA immunoreactivities in SCC had dot‑like staining patterns in the nuclei of partial and marginal cancer cells. In contrast, in BSCCs, SOX2 and PCNA had diffuse staining patterns in almost all cancer cells. SOX2 overexpression had little effect on the expression levels of claudin‑4, occludin and PCNA. It also had little effect on the cell proliferation of HSC2 and HSC3 cells. Differences in immunoreactivity and staining pattern may be valuable to distinguish between BSCC and SCC in diagnosis.

Abstract
BACKGROUND Metastatic basaloid squamous cell carcinoma is a fatal, high-grade variant of squamous cell carcinoma that is extremely rare in the oral cavity. We present a rare case of metastatic basaloid squamous cell carcinoma arising from the hypopharynx with pulmonary and brain metastases. Recognizing this diagnostic subtype is of critical importance due to the aggressive nature and high incidence of recurrence, lymph node metastases, and mortality. CASE REPORT A 42-year-old male arrived at the Emergency Department reporting a 1-week headache. Six months prior, he reported throat pain and neck swelling. Triple endoscopy revealed a large ulcerative tumor. A carbon dioxide laser procedure debulked and removed the mass. Incisional biopsy with histopathology was consistent with invasive basaloid squamous cell carcinoma. Computed tomography (CT) of the neck with contrast demonstrated bilateral cervical level II/III necrotic adenopathy, and CT chest with contrast demonstrated bilateral pulmonary nodules. The patient completed chemoradiation therapy with cisplatin; however, repeat CT chest revealed enlarging intrapulmonary metastases. CT brain without contrast demonstrated a central brainstem lesion. The patient started treatment with pembrolizumab. On day 14 of treatment, he presented to the Emergency Department again for headache. MRI of brain with contrast demonstrated a new lesion with vasogenic edema. Intravenous dexamethasone was started and the decision to pursue stereotactic radiosurgery was made. CONCLUSIONS The diagnosis of basaloid squamous cell carcinoma in the setting of intrapulmonary and brain metastases is an extremely rare, high-grade bimorphic aggressive variant of squamous cell carcinoma that needs to be histopathologically differentiated from other tumors. Given its high mortality rate and poor prognosis the decision to pursue further treatment versus aggressive palliative care should be discussed.

Abstract
We characterize the clinicopathological features of two patients (one 38 year old woman and one 42 year old man, both of Chinese ethnicity) with Epstein Barr Virus positive non-keratinizing nasopharyngeal carcinoma from an endemic region with prominent presence of amyloid and one case with both amyloid and abundant intracytoplasmic hyaline globules. The amyloid material was positive for Congo red and showed apple green birefringence when examined under polarized light. The amyloid was immunoreactive for cytokeratins and was located both intra- and extracellularly. Frequently the amyloid had a light microscopical spherical appearance and displayed peripheral radiating fibrils from a central homogenous core. One of the patients had a unique presentation of nasopharyngeal carcinoma with perceived hemoptysis and coughing up two pieces of tumor tissue. In reality, the nasopharyngeal tumor was polypoid and the two fragments were pinched of from the main tumor mass.
