[PMID: 37690277 PMCID: PMC10507190 DOI: 10.1016/j.ijscr.2023.108791] [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: 08/17/2023] [Revised: 09/01/2023] [Accepted: 09/02/2023] [Indexed: 09/12/2023] Open
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.

Abstract
Aims We report a case of pulmonary basaloid carcinoma with bronchiolo-alveolar cell differentiation. Patients and Results A 75 year-old presented with a tumor measured 2.0 cm and was located in the periphery of the left upper lobe. Histologically, the lesion consisted of nests of basaloid cells, and lumina and clefts lined by tumor cells with features of mucous cells or type II pneumocytes or with mixed features. Conclusions Previously reported basaloid carcinomas of the upper aero-digestive tract and lung have been purported to have an aggressive behavior. The tumor in the present study had features of a histopathological low grade tumor including a low mitotic rate, no tumor necrosis and a growth pattern at the periphery similar to that of bronchiolo-alveolar carcinoma.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a rare, aggressive and distinct variant of squamous cell carcinoma (SCC) of the upper respiratory and digestive tract. We have evaluated disease specific survival (DSS) and overall survival (OS) through Kaplan-Meier method and mortality risk through univariate statistical analysis of Cox in 42 cases of BSCC and other 42 of laryngeal SCC (LSCC) matched for both age and sex. We demonstrated that laryngeal BSCC is a more aggressive tumor than LSCC as is associated to higher nodal recurrence of pathology (5 vs 2 patients, overall risk, OR 2.7), a reduced survival (median survival 34 vs 40 months, OR 3.2 for mortality); in addition, basaloid patients have a higher risk to be affected by second primary tumors (13 vs 3 patients, OR 5.8) and a higher probability to die for this second tumor (Hazard Risk, HR 4.4). The analysis of survival shows an increased mortality risk concurrent with the parameters assessed by univariate analyses that assume a predictive and statistical significance in second tumor and grading in basaloid LSSC.

Abstract
Basaloid squamous cell carcinoma is a well-established anatomopathologic entity of the upper aerodigestive tract and is more aggressive than the conventional squamous cell carcinoma. Only seven cases of this variant have been reported in the esophagus. Two cases of basaloid squamous carcinoma in the middle and lower third of the esophagus in two men aged 59 and 60 years are presented. Tumor stages were IIA and IV at the time of total esophagectomy, and survival times were 34 and 4 months, respectively. Histologically, the two tumors were composed of nests of cells with a basaloid appearance, the first with a predominantly cribriform pattern and the second with a solid lobular pattern and intense comedonecrosis; in the adjacent squamous epithelium of both tumors, carcinoma in situ was observed focally. Immunoreactivity was poor for high-molecular-weight cytokeratins and absent for those of low molecular weight. Staining for epithelial membrane antigen was weakly positive, enolase was moderately positive, and no reactivity for carcinoembryonic antigen, S100 protein, and chromogranin was observed. The flow cytometric analysis showed both tumors to be hyperdiploid with an index of cell proliferation of over 50%.

Abstract
Primary mucosal melanomas of the head and neck are rare. In addition, second primary mucosal melanoma following primary cutaneous malignant melanomas is very rare. We report a second primary mucosal melanoma. A 76-year-old woman, who had a previously cutaneous malignant melanoma of the left foot, visited with a complaint of a foreign body sensation of the throat. Endoscopy revealed a black mass at the left piriform sinus of the hypopharynx. After wide surgical excision of the lesion and reconstruction with a radial forearm free flap, the histopathology was confirmed to be a second primary mucosal malignant melanoma of the hypopharynx. Five months postoperatively, masses were palpated in the neck, and metastasis was diagnosed. The patient was treated with adjuvant chemotherapy and radiotherapy. Eight months postoperatively, computed tomography scans showed other metastatic masses in the liver, spleen, both adrenal glands, soft tissues of the abdominal wall, and both lungs. After that, the patient died 9 months postoperatively. We report a rare case of second primary mucosal malignant melanoma of the hypopharynx. Although rare, this case shows that a detailed examination of the hypopharynx and the head and neck should be a part of the follow-up examination in all cutaneous malignant melanoma patients.

Abstract
The most common type of malignancy affecting the upper aerodigestive tract is squamous cell carcinoma. Basaloid squamous cell carcinoma (BSCC) is a rarely seen, high-grade, bimorphic variant of squamous cell carcinoma, which displays distinct histological features. This entity was first described by Wain et al. in 1986. Since then, approximately 170 cases of head and neck basaloid squamous cell carcinoma have been reported. Tonsils are an uncommon site of occurrence of basaloid cell carcinoma. Only 10 cases of basaloid squamous cell carcinoma arising in the tonsils have been described in current English literature. Histopathologically, these carcinomas are characterised by the presence of a basaloid component in close association with squamous cell carcinoma. In this article, a case of BSCC of the tonsil is reported. The clinical and histopathological features of this tumour are discussed. Relevant literature has been reviewed and differential diagnosis of this tumour is discussed.

Abstract
AbstractObjective:To evaluate the clinical course and pathological characteristics of basaloid head and neck squamous cell carcinoma.Method:Retrospective study of 18 cases of basaloid head and neck squamous cell carcinoma. Epidemiological, clinical and histological data were analysed and the Kaplan–Meier test used to estimate survival rates.Results:The majority of lesions were at an advanced stage. These lesions were primarily localised in the larynx, hypopharynx and oropharynx. Routine pre-therapeutic assessment of squamous cell carcinoma was performed. Pathological diagnosis was difficult, although immunostaining was extremely useful. Positive staining for KL1, MNF 116 and 34βE12 and negative immunostaining for chromogranin and synaptophysin were also important factors in obtaining a definitive diagnosis. In the majority of cases, treatment involved surgery and radiotherapy. The five-year survival rate was 5 per cent.Conclusion:Basaloid squamous cell carcinoma is an uncommon head and neck lesion, with a challenging histological diagnosis. These lesions must be carefully monitored due to their aggressive course, and require multimodality treatment.

Abstract
The spectrum of pathological changes in anatomical sections of the hypopharynx ranges from benign pathologies to hypopharyngeal carcinoma. Beside the clinical status and the endoscopic evaluation performed by ear, nose and throat specialists, imaging techniques play an important role in pre-therapeutic and post-therapeutic diagnostics and in the follow-up of pharyngeal disease patterns, especially for malignant lesions. A conventional x-ray swallow examination, contrast-enhanced multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI), as well as positron emission tomography (PET) and positron emission tomography computed tomography (PET-CT) are applied depending on the medical question and disease. Especially in radiological oncology, it is extremely important in regions which are clinically difficult to assess to determine the exact localization and extent of hypopharyngeal pathologies to plan the optimal therapy for the patient. This article demonstrates the radiological appearance of pathological changes of the hypopharynx and discusses in particular the hypopharynx carcinoma in the focus of pre-therapeutic and post-therapeutic imaging.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a rare tumor representing an aggressive variant of squamous cell carcinoma (SCC) and arising from a common precursor cell. BSCC rarely originates from the sinonasal tract. We report on an 83-year-old woman with BSCC after multiple resections of an inverted papilloma (IP) of the left sinonasal tract. The tumor filled the nasal cavity completely and was infiltrating the ipsilateral frontal skull base and periorbita. Because of the tumor's expansion, the patient's age, and comorbidity, surgery was not performed, but primary radiotherapy was initiated. A possible association between sinonasal BSCC and IP, as implicated by the current case, must be further investigated. In any case, IP requires consequent endoscopic and, if necessary, radiological follow-up in order to detect recurrent disease or malignant transformation.

Abstract
We investigated the difference in the biologic nature of typical squamous cell carcinoma (SCC) and basaloid SCC (BSCC) of the larynx by studying proliferation and antiapoptotic markers. We performed an immunohistochemical analysis of the expression of proliferating cell nuclear antigen (PCNA) and bcl-2 protein in 15 patients with laryngeal BSCC and 15 stage-and site-matched controls with typical laryngeal SCC. We found no significant difference between the two groups in the PCNA index or the frequency of bcl-2 overexpression, nor did we find any significant difference in survival. Our findings indicate that the biologic nature of typical laryngeal SCC and laryngeal BSCC is similar. In addition, our follow-up data suggest that the clinical course of laryngeal BSCC is no worse than that of typical laryngeal SCC.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a rare and aggressive variant of cancer that mainly arises in the upper aerodigestive tract. This study reviews the clinico-pathological features and follow-up of a series of cases occurring in the head and neck. During a 32-year period (1974-2005), a total of 40 BSCCs have been diagnosed in the head and neck in our Institution. Males predominated in the series (35M/5F). The average age was 60.2 years (range, 40-85). Tobacco and alcohol consumption was found in more than 80% of the cases. Topographic distribution was as follows: larynx and hypopharynx, 22 cases (55%); oropharynx, 12 cases (30%); and oral cavity 6 cases (15%). The basaloid component predominated in 29 cases (72.5%). Vasculo-lymphatic invasion was detected in 5 cases (12.5%). Lymph node metastases were seen in 25 cases (62.5%, levels II and III in the neck dissection). Local recurrences appeared in 11 cases (27.5%) and distant metastases in 6 (15%). In 7 cases (17.5%) a second primary tumour was detected. The 2002 TNM staging was as follows: Stage I, 5 cases (12.5%); Stage II, 7 cases (17.5%); Stage III, 8 cases (20%), and Stage IV, 20 cases (50%). On follow-up, 21 cases (52.5%) are alive and 19 (47.5%) died of disease. Three- and 5-year overall survival was 50% and 38.5%, respectively. A significant shorter survival was detected in node positive patients (P<0.05).

Abstract
Hypopharyngeal cancers are usually squamous cell carcinomas (SCCs) that has the worst prognosis among the head and neck cancers. Overall, 5-year survival rate remains poor despite recent improvements in diagnostic imaging, radiation and chemotherapy, and improved surgical techniques. Hypopharyngeal cancers tend to present with advanced primary disease, and nodal metastasis is highly likely. The most important features determining prognosis are the size and extent of local spread of the primary carcinoma and the extent of involvement of regional lymph nodes. Distant metastasis at presentation is more common in hypopharyngeal cancers than in other head and neck cancers. Poor survival rate is partly due to emergence of second primary cancers but also to development of distant metastasis. Contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) remain the mainstay of initial radiological evaluation of hypopharyngeal cancer. Imaging usually results in upstaging of the tumor at presentation. Meticulous evaluation of the extent of the primary tumor with attention to spread to the subsites of the hypopharynx, larynx, and cartilage invasion are necessary for accurate staging. After surgery and radiation therapy, it is difficult with CT and MR to differentiate residual and recurrent tumor from edema and scarring. Fluorine 18-fluoro-deoxy-glucose -positron emission tomography (FDG-PET) has high sensitivity in detection of occult, residual, and recurrent tumors but has low specificity. Combined PET and CT increase specificity and are increasingly being used to image posttreatment cases. Other newer imaging modalities such as diffusion-weighted imaging (DWI), MR spectroscopy, and MRI with superparamagnetic iron oxide (SPIO) contrast agent are reported to be useful and should be used more widely in difficult cases.

Abstract
The epidemiological link between human papillomavirus (HPV) DNA and basaloid squamous cell carcinoma (BSCC) of the pharynx was studied. The expression of p53 protein was evaluated by immunohistochemical analysis. The presence of HPV DNA was evaluated by polymerase chain reaction amplification and "in situ" hybridization. The tobacco and alcohol consumption and the clinical outcomes of nine patients with BSCC of the pharynx are compared with site and stage matched 109 conventional squamous cell carcinoma (SCC) patients. The BSCC specimens were analyzed for the presence of HPV DNA and p53 expression. We did not find any significant differences in tobacco and alcohol consumption between patients with BSCC and patients with SCC. No HPV DNA was detected in BSCC, and p53 overexpression was found in five (55%) of the cases. Our results do not support an etiological link between HPV DNA and BSCC.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a highly aggressive neoplasm and a histologically distinctive variant of squamous cell carcinoma. Since the first description by Wain et al. in 1986, only 18 cases with BSCC in the nasal cavity or in the paranasal cavity have been reported in the English literature. We report herein two cases of BSCC of the maxillary sinus. Case 1 was 78-year-old man, who received preoperative radiotherapy and operation. He was alive without disease for 25 months after the operation. Case 2 was a 60-year-old man who received radiotherapy without operation. He died of lung metastasis 6 months after the initial diagnosis. We reviewed the clinical features of BSCC from the literature.

Abstract
We report a rare case of basaloid squamous cell carcinoma of the lung in a young Japanese woman. An 18-year-old woman presented with productive cough. Chest radiogram and computed tomography (CT) revealed a tumor in the left hilum accompanied by partial atelectasis of the left upper lobe and pleural effusion. Transbronchial fine-needle aspiration cytology supported a tentative diagnosis of primary squamous-cell carcinoma of the lung. The clinical stage was T4N2M1, with multiple bone metastases. Despite a transient response to chemotherapy consisting of carboplatin and paclitaxel, the patient died because of tumor progression 2 months after the start of the chemotherapy. Necropsy established the diagnosis of basaloid squamous-cell carcinoma of the lung. Immunohistochemical studies of the necropsy specimen indicated that the tumor was positive for keratin, vimentin, and S100, and negative for chromogranin A, cytokeratin CAM5.2, and bcl-2. Besides the rarity of the disease itself, the present case seemed to have additional uniqueness in that the patient was 18 years old and female. This is the youngest patient with a case of basaloid squamous cell carcinoma of the lung ever reported.

Abstract
Basaloid squamous carcinoma (BSC) is a rare variant of squamous cell carcinoma (SCC). In this study, clinicopathological and immunohistochemical characteristics of 12 superficial esophageal BSCs were examined and compared with those of typical superficial SCCs. Eight cases were classified into an elevated type, and the other four into a depressed type. High-grade intraepithelial neoplasia was not observed around the invasive lesions in five cases, and only BSC components were apparent. High-grade intraepithelial neoplasia was demonstrated in seven cases, five of which had both BSC and SCC components in the invasive lesion. A cribriform growth pattern, comedo-type necrosis, and hyaline deposits were conspicuous histological findings. CK14 was positively stained in 90% of the series, but the proportion of positive cells was small in most cases. Type IV collagen was increased or well preserved in the basement membrane in 70% of cases, but heparan sulfate was decreased in the majority. In comparison with SCCs, lymphatic permeation was observed less frequently. However, regarding the frequencies of venous permeation, nodal metastasis, p53 protein expression, and Ki-67 labeling index, no significant differences were noted. Thus, esophageal BSCs demonstrate the pathological features characteristic of an early stage, but pathological parameters related to biological behavior do not significantly vary from those typical of SCCs.

Abstract
PURPOSE OF REVIEW Basaloid squamous cell carcinoma is an uncommon variant of squamous cell carcinoma and was first described as a distinct entity in 1986. Basaloid squamous cell carcinoma seems to have a poorer survival rate than classical squamous cell carcinoma. On the basis of a critical literature survey, we attempt to evaluate if basaloid squamous cell carcinoma is really more aggressive and presents a poorer outcome than squamous cell carcinoma. RECENT FINDINGS All papers are retrospective, and most include small numbers of cases, which are further diminished when subdivided according to specific sites. Only in three studies was basaloid squamous cell carcinoma of the head and neck region compared with matched squamous cell carcinoma controls. These studies did not show a uniform tendency regarding the aggressiveness and outcome of basaloid squamous cell carcinoma. In addition, several recent papers confirmed the presumed greater aggressiveness and worse outcome, and other recent papers questioned these characteristics. SUMMARY The presented literature survey does not permit conclusions regarding the aggressiveness and outcome of basaloid squamous cell carcinoma compared with squamous cell carcinoma. Greater numbers of basaloid squamous cell carcinoma should be studied and compared with site-matched, stage-matched, and age-matched controls of conventional squamous cell carcinoma.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a recently recognized high-grade tumor with a propensity for nodal as well as systemic metastasis and can arise from different anatomic locations. The differential diagnosis includes adenoid cystic carcinoma, small cell neuroendocrine carcinoma and squamous cell carcinoma. Monoclonal antibodies reactive with cytokeratin (34betaE12, AE3, pancytokeratin), as well as other cellular antigens (vimentin [VIM]; synaptophysin [SYNF]; chromogranin A [ChA]; neuron-specific enolase [NSE]; S-100, desmin, smooth-muscle actin [SMA]), were used in an immunoperoxidase method with paraffin-embedded tissue to phenotypically characterize a case with features of BSCC arising in the maxillary sinus. Neoplastic cells reacted with the high-molecular-weight cytokeratin antibody 34betaE12, as well as with other antikeratin antibodies, but failed to react with the antibodies VIM, desmin and SMA and showed variable immunoreactivity for NSE, SYNF and S-100. The staining pattern for NSE was diffuse and intense and reactivity for ChA was inconsistent.

Abstract
Oesophageal basaloid squamous cell carcinoma (BSCC) is uncommon and has been reported to have a worse prognosis than squamous cell carcinomas (SCCs), but this tumour has not been fully characterized. The aim of the present study was to analyse the clinicopathological features of a large cohort of patients with oesophageal BSCC treated at a single institution. The pathology of 756 primary oesophageal cancers treated between January 1989 and December 1998 was reviewed. Tumours that fulfilled the diagnostic criteria of BSCC were identified and were compared with SCC. Their expression of MIB-1, DNA ploidy, and telomerase activity were also studied. Thirty Chinese patients (25 men and five women) with BSCC were found, comprising 4% of patients with oesophageal cancer treated by surgical resection in the study period. Their median age was 67 years (range 40-78 years). Dysphagia was usually the main presenting symptom. Other concomitant malignant tumours were seen in three patients and paraneoplastic glomerulopathy in one. Five tumours were located in the upper third, 19 in the middle third, and six in the lower third. The median length was 5.8 cm (range 2-12 cm). The median MIB-1 score of BSCC was 750 (range 400-858) and was higher than that of SCC (p=0.003). The primary tumour and metastatic BSCC were aneuploid, as detected by flow cytometric analysis in nine patients. Telomerase activity was positive in 95% (19 out of 20) of the cases analysed. The 5-year survival of patients with BSCC was 12%. Distant metastases were seen in 53% (n=16); lung and liver were the most common sites. The median survival of patients with tumours which had a high level of telomerase activity was significantly shorter than those with low levels of telomerase activity (1 vs. 27 months) (p=0.001). The median survival of patients with BSCC and SCC was 26 and 16 months, respectively (p=0.3). In conclusion, BSCC has distinctive clinicopathological features and its long-term prognosis is no worse than SCC. The level of telomerase activity may have a prognostic role.

Abstract
INTRODUCTION Basaloid squamous carcinoma (BSC) of the head and neck is an uncommon, recently described variant of epidermoid carcinoma. BSC appears biologically with a greater propensity to local aggressiveness and metastatic potential than the conventional type. OBJECTIVES To determine the incidence of BSC of the larynx and hypopharynx in our area, and to evaluate its behavior and prognosis. PATIENTS & METHODS 272 cases of squamous carcinoma of the larynx and hypopharynx were reviewed and 6 diagnosis of BSC were made, corresponding to 6 tumors in 5 patients. Their clinical records were analyzed. An immunohistochemical study was performed, including antibodies against cytokeratins (CK 7, CK 8, CK 19, CK 20, CK 1, 10, 5, 14, y CK 10), epithelial markers (EMA, CEA, Ber-EP4), vimentin and three neuroendocrine markers: neuron-specific enolase, chromogranin and synaptophisin. Bcl-2 expression was also investigated. RESULTS Most tumors were supraglottic. 5 out of 6 tumors were clinically benign, without any metastases or recurrence after exclusive surgical resection and a follow-up ranging 42 to 142 months. We detected a trend toward a primitive pattern of keratin expression. All tumors were stained with EMA and CEA MoAbs, but we could not find Ber-EP4 nor endocrine markers staining in any of them. However, BCL-2 expression was widely found in 4 out of 5 tumors immunostained. CONCLUSION It seems to be a progressive dedifferentiation of the basaloid cell component, probably a subpopulation with more primitive features responsible of the aggressiveness reported in the literature. However, the surprising good prognosis in most of our cases makes necessary more studies and wider series to confirm our data.

Abstract
Twenty-three cases of basaloid squamous cell carcinoma (BSCC) and 23 stage-matched pairs of typical squamous cell carcinoma (SCC) of the oesophagus were investigated for molecular aberrations. Polymerase chain reaction (PCR) was used to detect loss of heterozygosity at the APC, RB, and MCC gene loci, while differential PCR was carried out to detect amplification of the CDK4 gene. In addition, the level of expression of the p53 and RB proteins in the tumour tissue was assessed by immunohistochemistry. Loss of heterozygosity (LOH) at the APC and MCC loci was about twice as common in BSCC as in SCC (40% vs. 21% and 33% vs. 12%, respectively), with co-existence of LOH at both loci occurring only in BSCC. LOH frequency at the RB gene locus was not remarkably different in either BSCC or SCC (20% vs. 24%, respectively). On immunohistochemistry, accumulation of p53 protein was slightly more frequent in BSCC than in SCC (61% vs. 52%), whereas the rate of loss of RB protein expression was about equal in both types of carcinoma (9% vs. 13% BSCC and SCC, respectively). There was no detectable amplification of the CDK4 gene in either type of tumour. Although the observed differences did not achieve statistical significance, this work has further highlighted possible differences between the molecular pathogenesis of BSCC and SCC.

Abstract
OBJECTIVE/HYPOTHESIS Basaloid squamous cell carcinoma (BSCC), an uncommon tumor with predilection for the upper aerodigestive tract, is a distinct variant of squamous carcinoma, because of its unique histological features and ominous clinical behavior. This study reviews the experience in treating BSCC from two institutions. STUDY DESIGN Retrospective. METHODS H&E-stained sections from 20 patients with BSCC of the head and neck were reviewed and clinical follow-up was obtained for all patients. RESULTS The study group consisted of 14 male and 6 female patients. Their ages ranged from 43 to 85 years, with a mean age of 62 years. Sites of origin included the larynx (4), tongue (3), pyriform sinus (3), nose (2), floor of mouth (2), mastoid (1), tonsil (1), epiglottis (1), nasopharynx (1), trachea (1), and palate (1). Pain was the most common presenting symptom (5 cases), followed by hoarseness and bleeding (3 cases each). Tobacco and alcohol abuse was noted in 17 patients. Treatment modalities included surgery with or without chemotherapy or radiotherapy in 13 patients, chemotherapy with irradiation in 2, chemotherapy alone in 2, and radiotherapy alone in 3. Clinical follow-up revealed no evidence of disease in 11 patients. Four were alive with disease at the time of writing and five died of disease. CONCLUSION BSCC is a highly aggressive malignant tumor that presents in elderly patients who have a history of abuse of tobacco or alcohol, or both. Greater number of patients must be studied and compared with age-matched and stage-matched controls of conventional squamous cell carcinoma to determine whether the poor clinical outcome is related more to high-stage presentation or to the tumor's high-grade malignant cytological features.

Abstract
Most penile neoplasms are squamous cell carcinomas (SCC), but there are subtypes that show morphologic and possibly etiologic differences. Clinicopathologic features of 20 patients with basaloid carcinoma (BC), an unusual variant of squamous cell carcinoma, are presented. Median age was 52 years, and all tumors were located in the glans, three confined to the perimeatal region. Average tumor size was 3.8 cm. Microscopically, nests of small, basophilic cells with numerous mitosis were present. Human papillomavirus DNA sequences (type 16), using the polymerase chain reaction (PCR), were found in 9 of 11 cases. Differential diagnosis included urethral transitional cell, basal cell, small cell neuroendocrine, and metastatic carcinoma. Factors more significantly associated with regional metastasis and mortality were tumor thickness greater than 10 mm and infiltration of the corpus cavernosum. A comparison with typical squamous cell carcinoma showed basaloid carcinoma to have a higher histologic grade, a deeper invasion of penile anatomic levels, and a higher mortality rate. Of 17 patients observed, 10 were dead of disease (average time, 34 months), one was alive with disease 6 months after diagnosis, and 5 were alive and free of disease (average time, 71 months); the remaining patient died of other causes. Basaloid carcinoma is a distinctive morphologic subtype of squamous cell carcinoma frequently associated with the human papilloma virus.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a recently described bimorphic variant of squamous cell carcinoma with distinct morphological and biological features. We describe the clinicopathological findings, along with immunohistochemical and ultrastructural investigations, in 15 new cases of BSCC of the larynx or hypopharynx observed and treated at the otolaryngology department of the University of Padua between 1989 and 1995. The world literature is also reviewed in order to develop a more accurate clinicopathological profile of the tumor. Patient records and histologic slides were reviewed in all of our 15 cases. The patient group consisted of 13 men (86.67%) and 2 women with a mean age of 63.33 years (median 69 years; range 44 to 84 years). Nine patients presented with cervical lymph node metastases. Surgical treatment was the therapy of choice; radiotherapy and chemotherapy have been applied in different combinations. Follow-up was available on all 15 cases. Local recurrence was described in 3 cases. Five of the 9 patients with cervical lymph node metastases developed distant metastases. Distant spread of the tumor without lymph node involvement was observed during follow-up in 4 cases. Nine patients died of disease, 2 are alive with widespread metastases, 2 are alive with no evidence of disease, and 2 have died of other causes. The determined 5-year survival was estimated to be 17.5% by the Kaplan-Meier method. In conclusion, BSCC is a distinctive carcinoma that is important to recognize, because it has a more aggressive biological behavior than conventional squamous cell carcinoma.

Abstract
In the present study, the expression of bcl-2 protein in esophageal squamous cell carcinoma (SCC) and basaloid carcinoma (BC) was immunohistochemically examined, and its relation to tumor progression and postoperative survival was determined in SCC. A total of 42 SCC and 4 BC tumor samples were fixed with formalin, embedded in paraffin, and stained using monoclonal bcl-2 protein antibody, clone 124. Immunoreactivity was semiquantitatively scored, and the staining results were compared with the pathologic features and survival rates. The cytoplasm of basal cells from the normal esophageal epithelium was stained. In some well- and moderately differentiated SCCs, bcl-2 protein-positive reaction was observed in the peripheral part of the tumor cord, but in poorly differentiated SCC, the cells were weakly or hardly stained. However, in BC, the cells were strongly stained. The immunoreactivity was positive in 45.2% of the SCCs and all of the BCs. There were no significant differences in pathological features or patient survival between the bcl-2 protein-positive and protein-negative SCCs. In conclusion, the expression was not related to tumor progression and had no prognostic significance in SCC. Conversely, BC had strong immunohistochemical expression, probably associated with the differentiation of carcinoma cells simulating the basal cells of the esophagus.

Abstract
Basaloid squamous carcinoma (BSC) is a rare neoplasm. We present a case of basaloid squamous carcinoma of the larynx in a 57-year-old male patient. The diagnosis before treatment was supraglottic carcinoma (T3N1MO) and biopsy of the larynx revealed a poorly differentiated squamous cell carcinoma. Total laryngectomy and right radical neck dissection were performed, and pathological studies of a specimen removed from the larynx revealed BSC of the larynx. The patient's postoperative progress was uneventful, however, 12 months later he developed lung metastasis of the left side. The patient underwent partial resection of the lung. He developed recurrence of lung metastasis 6 months later. Chemotherapy with cisplatin (CDDP) and vindesine sulfate (VSD) was administered in two courses, but the efficacy was evaluated as no change (NC). At present, 26 months after the first visit, he has been asymptomatic with lung metastasis, and there was no evidence of recurrence in the neck.

Abstract
The basaloid squamous cell carcinoma (BSCC) is a variant of squamous cell carcinoma, having histologically distinctive features and appearing in the oral cavity, upper respiratory tract and esophagus. Histological hallmarks are the presence of a basaloid component in intimate association with squamous cell carcinoma. The basaloid component is characterized by tightly packed nests of cells with scant cytoplasm and hyperchromic nuclei without visible nucleoli and an increased mitosis rate. Basaloid squamous cell carcinoma is said to have a higher malignant potential than common oral squamous cell carcinoma with an increased incidence of regional lymph-node metastases and distant metastases. Our finding of a Ki-67 index of 30% and the immunohistochemical demonstration of p53 protein speaks well for enhanced aggressive biological behavior. The differential diagnosis includes the adenoid cystic, mucoepidermoid, neuroendocrine, adenosquamous and conventional oral squamous cell carcinoma. Because of early dissemination, radical surgical treatment and additional radiation therapy are considered necessary. Our findings indicate that partial clinical and histological tumor regression occurs after systemic neoadjuvant chemotherapy.

Abstract
BACKGROUND Basaloid squamous cell carcinoma (BSCC) is a recently recognized, poorly differentiated variant of squamous cell carcinoma (SCC), which is located predominantly in the upper aerodigestive tract. METHODS In this study, clinical and pathologic parameters of 17 BSCCs and 133 typical SCCs of the esophagus that underwent potentially curative resection (no distant metastases, no residual tumor) were compared. In addition, light microscopic, electron microscopic, and immunohistochemical features of BSCC were investigated, to determine whether this type of carcinoma could be differentiated from other poorly differentiated carcinomas of the esophagus. RESULTS Light microscopic study showed that BSCC was composed of relatively small tumor cells, arranged in solid lobules with abundant comedo-type necrosis. BSCC was almost invariably accompanied by areas of concomitant typical SCC, foci of squamous cell differentiation, and/or severe squamous cell dysplasia or carcinoma in situ of the adjacent mucosa. Ultrastructurally, BSCC inconsistently showed features of squamous cell differentiation. Immunohistochemically, BSCC displayed poor reactivity for antibodies against wide-range cytokeratins and cytokeratin subtypes that are typical of squamous cell epithelia (cytokeratin 13 and cytokeratin 14). Infrequently, expression of Leu7, smooth muscle actin, and S-100 protein was found. In comparison with typical SCC, the characteristic features of BSCC were older patient age, higher proliferative activity (MIB-1 labelling index), and higher apoptotic indices. No differences were found with regard to pT classification, pN classification, tumor size, blood vessel invasion, lymphatic vessel invasion, neural invasion, or patient gender. Moreover, no differences in overall survival rates were found. CONCLUSIONS BSCC is a distinct histopathologic variant of SCC, characterized by a poor degree of differentiation and high proliferative activity. However, after potentially curative resection, the prognosis of patients with BSCC of the esophagus does not differ from that of patients with typical SCC.

Abstract
The basaloid-squamous carcinoma (BSC) that was first described in 1986 by Wain et al. for the head and neck region is a rare distinct variant of squamous cell carcinoma (SCC). The cardinal histopathologic feature is a biphasic cellular pattern of basaloid and squamous components. BSC has been confused with solid adenoid cystic carcinoma (ACC). Although the number of reported cases is small, BSC appears biologically virulent, with a propensity to aggressive local behavior, early regional and distant metastasis, and subsequent poor survival. We report the clinicopathological characteristics of 4 new cases and compare their immunohistochemical features with those of solid ACC and conventional SCC. Our results show that BSC, ACC and SCC react to CK 5/6. SCC is CK 10- and CK 13-positive, while BSC and ACC are negative for these markers. BSC and ACC react to CK 8, but in ACC only the luminal cells are CK 8 positive: therefore ACC has a glandular pattern. Our findings indicate that the immunohistochemical differences between BSC and ACC can facilitate their differential diagnosis. Because the biologic behavior of BSC differs from ACC and SCC, distinction among these tumor types is warranted.

Abstract
Basaloid-squamous carcinoma (BSC) of the esophagus is a rare but interesting neoplasm that occurs primarily in the upper aerodigestive tract. In this study, we reviewed 371 cases of esophageal malignancies and detected seven cases (1.9%) of BSC. The clinicopathologic features, light and electron microscopic findings, and immunohistochemical localization of various differentiation-related antigens, including cytokeratin (CK) subtypes, p53, and epidermal growth factor receptor (EGFR), were examined. DNA ploidy was also determined in an effort to characterize the biologic features of these tumors. The tumors were classified as stage I (n = 1), IIB (n = 3), III (n = 2) or IV (n = 1). Six patients had lymph node metastasis, in four the metastatic carcinoma exhibited basaloid components. Histologically, all the tumors displayed a biphasic pattern of basaloid and squamous components. The former predominated in three cases, the latter in four cases. All the tumors contained solid growth of basaloid cells with microcystic patterns and stromal hyalinosis as well as palisading of cells. Ultrastructurally, markedly replicated basement membrane was observed. Immunohistochemistry revealed staining with only CK 14 and CK 19 antibodies in the periphery of the basaloid tumor nests. These antibodies were also positive in the basal layer of normal esophagus. Diffuse immunoreactivity for EGFR was demonstrated in all the tumors. Five tumors displayed p53 nuclear immunoreactivity. All of the basaloid components demonstrated aneuploidy by DNA image cytometry. We conclude that BSC is a distinct type of esophageal carcinoma that should be differentiated from the usual types of esophageal carcinoma and may be associated with aggressive biologic behavior.

Abstract
Basaloid squamous cell carcinoma is a recently recognized variant of squamous cell carcinoma. The lesion is histologically distinctive and manifests a predilection for the supraglottis, pyriform sinus, and tongue base. The immunohistochemical profile is discussed. The differential diagnoses include adenoid cystic carcinoma, small cell neuroendocrine carcinoma, basal cell adenocarcinoma, adenosquamous carcinoma, squamous cell carcinoma, spindle cell squamous carcinoma, mucoepidermoid carcinoma, and adenoid squamous cell carcinoma. Basaloid squamous cell carcinoma is a biologically high-grade tumor with a propensity for nodal as well as systemic metastases. It is a morphologic and phenotypic entity with a separate prognostic significance.

Abstract
Basaloid squamous cell carcinoma is a variant of squamous cell carcinoma that was first described in 1986. In the English-language literature, only 26 cases of this infrequent histopathological entity have been reported in the larynx. Tumors have an aggressive biological behavior, justifying combined surgical treatment with radiotherapy. Two new cases are presented and the literature reviewed.

Abstract
BACKGROUND Basal cell carcinomas (BCCs) have been described in various locations, such as skin, anal canal, tongue, larynx, and recently, the lungs. These tumors seem to have a poor prognosis. METHODS A series of 115 surgically resected lung tumors, previously classified as poorly or undifferentiated carcinoma, were reviewed retrospectively. From these, 37 cases were reclassified as BCCs and were compared in terms of clinical features and survival, with 40 cases reclassified as poorly differentiated squamous cell (PDSC) carcinoma of the lung. RESULTS There was no difference between the groups regarding age, clinical presentation, pattern of relapse, and cause of death. Median and overall survival were different between the two groups, especially for Stage I and II patients: 5-year actuarial survival in the BCC group was 15% and in the PDSC group 47% (P = 0.004). CONCLUSIONS This subset of non-small cell lung cancer (NSCLC) has a worse prognosis than other NSCLC, and this should be considered in survival studies and new treatment trials.

Abstract
A case of basaloid-squamous carcinoma of the esophagus in an 83 year old man is reported. The esophageal tumor showed a fungating growth at the junction of the middle and lower esophagus and was composed microscopically of submucosal multiple nests with solid and cribriform-like patterns accompanied with a small focus of squamous cell carcinoma adjacent to the overlying esophageal epithelium. The structural features closely resembled those of basaloid-squamous carcinoma. The submucosal tumor cells were immunohistochemically positive for epithelial membrane antigen, wide spectral keratin, alpha actin and S-100 protein. By electron microscopy, the tumor cells had microvilli, desmosomes and bundles of myofilaments, and replicated basement membranes were frequently observed adjacent to the nests. The positive immunoreaction of S-100 protein and alpha actin and the existence of bundles of myofilaments indicated that the present tumor did not correspond well with basaloid-squamous carcinoma. In addition, there was no evidence of true glandular lumina in the tumor nests, a finding which was inconsistent with that of adenoid cystic carcinoma. From the immunoreactivity of S-100 protein and ultrastructural features, it was considered that the present submucosal tumor had originated from undifferentiated pluripotential primitive cells, which differentiated to myoepithelial cells.

Abstract
INTRODUCTION We describe the clinicopathologic and flow cytometric features of 10 cases of basaloid squamous cell carcinoma (BSCC) of the head and neck to determine if DNA ploidy is a useful prognostic indicator. We also provide a review of 80 cases previously reported in the English language literature. MATERIALS AND METHODS The 10 cases were obtained from the surgical pathology files of Presbyterian University Hospital and The Eye and Ear Institute, Pittsburgh, PA (1987-1991). In all 10 cases, the microscopic slides and clinical data were reviewed. Flow cytometry was performed using the Hedley technique and formalin-fixed, paraffin-embedded tissue. RESULTS The mean age of patients with BSCC was 64 years (range, 49 to 75 years). Tumor involved the base of tongue (n = 5), hypopharynx-epiglottis (n = 3), and tonsil (n = 1). One case presented with cervical lymph node metastasis from an unknown primary site. Histologically, BSCC showed a biphasic pattern with basaloid-squamous elements, comedonecrosis, stromal hyalinization, surface dysplasia, and an in situ and/or invasive squamous cell carcinoma component. Flow cytometry revealed six diploid and four aneuploid tumors. Five of six patients with diploid and all four patients with aneuploid tumors developed early regional and/or distant metastases. Of the two patients who died of disease, one had a diploid and the other an aneuploid tumor. CONCLUSION Our study reaffirms the predilection of BSCC for the base of tongue, pyriform sinus, and supraglottic larynx, and its aggressive biologic behavior with a high incidence of cervical lymph node metastasis (64%), distant spread (44%), and death from disease (38% mortality at 17 months median follow-up). However, in contrast to previous reports, tumor ploidy by flow cytometry provided no additional prognostic information beyond that supplied by routine histologic evaluation.

Abstract
During a 16-year period (1974-1989), a retrospective review of 468 surgical specimens of laryngectomy yielded 7 cases (0.66%) of basaloid-squamous cell carcinoma. They were all males between 42 and 63 years of age. Four cases were supraglottic and one transglottic. The other two arose in the left pyriform sinus and vallecula, respectively. At diagnostic time, 4 cases were Stage III and 2 Stage IV, only one being Stage II. Glanz index of histologic malignancy was high (> 5) in most cases (6/7). Mitotic rate was also high (22-78 mitoses/10 HPF). Lymph node metastases were documented at diagnosis in 5 cases, 3 of them presenting with extracapsular extension. One case developed liver metastases. During the follow-up, lymph nodes of the neck were again metastasized in 4 cases, and stomal recurrence was present in another one. Death of disease was confirmed in 5 cases after 10 to 35 months of follow-up. Overall survival was 28.5% after 3 years.

Abstract
BACKGROUND Only five cases of basaloid squamous cell carcinoma (BSCC), a rare tumor of head and neck, have been reported to involve the floor of mouth. METHODS Clinicopathologic and immunohistochemical features of eight BSCC of floor of mouth were studied to evaluate the significance of the basaloid features. RESULTS Five patients were male and three were female. Their mean age was 52 years (range, 39-59). At presentation, one patient was diagnosed with Stage II disease, four were diagnosed with Stage III disease, and three were diagnosed with Stage IV disease. Aside from typical squamous differentiation, each patient had a component of basaloid cells arranged in irregular nests, cords, or pseudoglandular spaces with a brisk mitotic rate, myxoid stroma, and marked tendency for perineural invasion. A panel of immunostains yielded the following results: keratin, +8/8; carcinoembryonic antigen, +3/8; and S-100, chromogranin, and neuron-specific enolase were negative. Mucin stains were negative in all cases. Ultrastructural characterization of three BSCC revealed squamous differentiation of the basaloid cells and a peculiar basal membrane-like material in between them. No neurosecretory granules were present. Seven patients underwent surgery; six of them were also treated with postoperative radiation therapy. In two cases, chemotherapy was added at recurrence. One nonresectable patient received radiation and chemotherapy. At the last follow-up, five patients were dead of disease within 13 months from the diagnosis. One patient died of an unknown cause. Two patients were still alive at the time of this report, 4 and 2 months after treatment. Seven patients had recurrent disease. The authors compared these data with a control group of patients with conventional squamous cell carcinoma (SCC). CONCLUSIONS The authors' results indicate that BSCC of floor of mouth is an aggressive variant of SCC and is prognostically worse than the conventional SCC, regardless of the grade of the latter.

Abstract
Basaloid squamous cell carcinoma (BSCC) of the head and neck is a recently described high-grade variant of squamous cell carcinoma. It is a biologically virulent neoplasm with a propensity for nodal, as well as systemic, metastases. Because of the limited number of published reports, we reviewed data from patients of the University of Virginia Health Sciences Center and identified 16 cases of BSCC. The intent of this study was to determine the role of radiotherapy in the treatment of BSCC and better define the clinical features of this entity. Radiotherapy alone, or in combination with surgery, resulted in excellent local control rates. Distant metastases, chiefly pulmonary, occurred in more than half of the patients.

Abstract
On review of 115 poorly or undifferentiated lung cancers from 671 lung tumors resected over a 7-year period, we have found 38 cases of basaloid carcinoma. The cardinal histopathologic features distinguishing this tumor from other non-small cell lung cancers are a lobular growth pattern of small cells with moderately hyperchromatic nuclei, with no prominent nucleoli, and with scant cytoplasm, a high mitotic rate, and peripheral palisading. Basaloid carcinoma was present in a pure form in 19 cases and the other 19 tumors were of a mixed, but prominent, basaloid type associated with squamous cell carcinoma, large cell carcinoma, or adenocarcinoma. The immunophenotype of basaloid cancers was close to that of basal bronchial epithelial cells, with a low level of expression of low molecular weight cytokeratins. Staining for neuroendocrine markers was infrequent and inconsistent. Ultrastructural study showed an absence of neurosecretory granules and the presence of some squamous and/or glandular differentiation. This morphologic and immunologic phenotype suggests that basaloid carcinoma is derived from a pluripotent reserve cell or a basal bronchial epithelial stem cell. This unique histologic form of lung tumor has a poor prognosis, with a median survival rate of 22 months for stage I and II disease. This justifies classification of basaloid carcinoma as a distinct form of lung cancer, separate from small cell lung carcinoma.
