Abstract
CONTEXT Squamous cell carcinoma of the upper aerodigestive tract is a heterogenous entity. Although conventional squamous cell carcinomas are easily recognized, the morphologic variants of squamous cell carcinoma can present a diagnostic challenge. Familiarity with these variants is necessary because many are associated with unique risk factors and are characterized by specific molecular alterations (eg, nuclear protein in testis midline carcinomas). Perhaps the most important distinction is in identifying viral-related from nonviral-related carcinomas. The accurate diagnosis of these variants is necessary for prognostic and therapeutic reasons. OBJECTIVES To provide a clinicopathologic overview and summary of the molecular alterations of the common squamous cell carcinoma variants, including verrucous, spindle cell, acantholytic, adenosquamous, basaloid, and papillary squamous cell carcinoma, as well as nuclear protein in testis midline carcinoma, and to discuss the distinguishing features of human papillomavirus- and Epstein-Barr virus-related squamous cell carcinomas. DATA SOURCES Published peer-reviewed literature. CONCLUSIONS Familiarity with squamous cell carcinoma variants is essential for proper diagnosis and to guide appropriate clinical management. Further insight into the molecular alterations underlying those variants may lead to alterations in existing treatment approaches and to evolution of novel treatment modalities.

Abstract
Basaloid squamous cell carcinoma (BSCC) is a rare variant of SCC having a marked predilection for the upper aerodigestive tract. It is regarded as a high-grade tumour with increased propensity for metastasis to distant sites. The histological hallmark of BSCC is its dimorphic pattern of presentation with a characteristic basal cell component associated with squamous component. We report two cases of BSCC on the buccal mucosa and gingiva, respectively, with the former presenting as a primary lesion in a patient without a positive history of tobacco and alcohol use and the latter present as a seemingly metachronous development from carcinoma lung. The proliferative index of the two diverse yet similar entities was assessed by Ki-67 labelling index (LI) and the association of human papillomavirus (HPV) was detected with p16 monoclonal antibody. The intrinsically aggressive behaviour of BSCC and its association with HPV is highlighted.

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
Basaloid squamous carcinoma is a rare distinct histologic variant of squamous cell carcinoma of the head and neck region. Basaloid squamous carcinoma is more aggressive and has a poorer prognosis, although histologically, it is associated with squamous cell carcinoma and squamous atypia. The usual site of occurrence for basaloid squamous carcinoma is the base of the tongue, hypopharynx (pyriform sinus), and the supraglottic larynx (Wain et al. Hum Pathol 1986;17:1158-1166). We are reporting an unusual case of basaloid squmous carcinoma of the mandible with no secondaries and features of sarcomatoid pattern histologically.

Abstract
BACKGROUND Basaloid squamous cell carcinoma (BSCC) is an uncommon, high-grade variant of squamous cell carcinoma (SCC) of the head and neck. Its poorer prognosis compared with common SCC remains controversial. The authors investigated the outcomes of patients with BSCC who received radiotherapy and compared them with the outcomes of patients with SCC. METHODS From 1994 to 2004, 1007 patients received radiotherapy for head and neck carcinoma with lymph node involvement. The histologic types consisted of 51 BSCC, 431 poorly differentiated SCC (PSCC), and 525 well or moderately differentiated SCC (WMSCC). A case-control analysis was performed with BSCC matched against both PSCC and WMSCC to compare disease-control and survival rates. RESULTS Patients with BSCC received treatment modalities similar to those received by patients with SCC: They received induction chemotherapy (12%) or concurrent chemotherapy (33%), and a median radiation dose of 70 Gray. Posttreatment viable tumor was present in 44%, 13%, and 28% of neck dissection specimens from patients with BSCC, PSCC, and WMSCC, respectively. The 5-year disease-free survival rates (63%, 77%, and 76%, respectively) and overall survival rates (85%, 70%, and 71%, respectively) demonstrated no statistically significant differences for BSCC, PSCC, or WMSCC, respectively. CONCLUSIONS In this study, a poorer prognosis could not be demonstrated for irradiated patients with BSCC compared with either PSCC or WMSCC. All patients in this study had positive lymph node status, and the majority of patients (84%) had oropharyngeal cancer. The BSCC cohort did have a relatively high rate of viable tumor in their posttreatment neck dissections, and they had a relatively high rate of distant disease. On the basis of the high rate of lung metastases and the possibility of efficient salvage, the authors recommend obtaining a chest computed tomography scan during initial staging and follow-up.

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
Basaloid squamous carcinoma is a rare variant of squamous cell carcinoma. It is frequently diagnosed at an advanced stage with metastases. Histologically, it is identical to basaloid carcinoma at other anatomical sites. Some authors suggest that it may be associated with second primary tumors. Others implicate the Epstein-Barr and human papilloma viruses. All reports but one warn of its aggressive biological behavior. Our case concerns a 52-year-old man who had a small lesion in his right cord. Biopsy of the lesion was performed twice, and conventional squamous cell carcinoma was diagnosed; the patient returned 2 months later with progressed metastatic disease. The patient underwent a laryngectomy and a complete clinical and immunohistochemical investigation. Basaloid squamous carcinoma is a totipotential neoplasm with a grave prognosis. It can be misdiagnosed; therefore, the authors would like to emphasize the significance of this condition in comparison to conventional squamous cell carcinoma, and we provide a review of the relevant recent literature.

Abstract
Background Very few reports have investigated the role of cell cycle regulators as biomarkers in Basaloid Squamous Cell Carcinoma (BSCC) of the larynx, a definite morphologic, uncommon, very aggressive variant of squamous cell carcinoma. Lower expression of Ki67/Mib-1, a proliferation marker highly expressed in the majority of tumours, and p53, a tumour suppressor protein that can induce an arrest of the G1-S transition, was related to a better prognosis in laryngeal BSCC. In the head and neck, p27kip1, a member of the Cip1/Kip1 family of cyclin-dependent kinase inhibitors, has emerged as an independent prognostic factor, able to identify low-expressing tumours with unfavourable course. Up to date the role of this protein was never studied in BSCC. Aim of our study was to investigate the potential prognostic value of p27kip1 levels and their correlation with Ki67/Mib-1 and p53 expression in BSCC of the larynx. Methods The retrospective study group consisted of 15 male and 1 female patients, affected by laryngeal BSCC, ranging in age from 44 to 69 years (mean 58). The tumour originated from the supraglottis in thirtheen cases and from the glottis in the remaining three. Ten patients had metastatic cervical lymph nodes at presentation and were classified as N+. Post surgical stage was IV in four patients, III in nine, II in two cases and I in the remaining one. Follow-up ranged from a minimum of 5 months up to 9 years. Paraffin-embedded tissue sections of each laryngeal tumour were analyzed for p27kip, Ki67/Mib-1 and p53 expression by immunohistochemistry. Results The immunohistochemical study showed p27kip1 expression in 40% of the patients with no evidence of disease (NED) and in none (0%) of the patients dead of disease (DOD), whilst p53 was expressed in 60% of patients in NED status and in 90% of patients in DOD status. Ki67/Mib-1 was positive in 80% of NED patients and in 100% of DOD patients. At multivariate analysis, performed by means of Discriminant analysis, low levels of p27kip1 expression significantly correlated with poor prognosis (P < 0.05). Conclusion p27kip1 protein has been shown to be a significant independent prognostic factor in laryngeal SCC. In our series of laryngeal BSCC the resulting data seem to confirm the clinical prognostic relevance of p27kip1 low expression, which directly correlated with biological aggressiveness and consequent shortened survival.

Abstract
INTRODUCTION Basaloid is a rare and poorly-differentiated variant of squamous cell carcinoma of the larynx, with an invasive solid growth of cells in a lobular configuration. Different molecular markers, such as p53, Ki-67 and E-cadherin, have been shown to be prognostic factors in head and neck cancer. OBJECTIVE To evaluate the relationship between the immunoexpression of p53, Ki-67 and E-cadherin in relation to prognosis in basaloid squamous cell carcinoma of the larynx (BSCCL). PATIENTS AND METHODS We retrospectively studied 11 cases of BSCCL, all male with a mean age of 62.4 years. Immunohistochemical analyses were performed on paraffin-embedded tissues using p53 (DO- 7), Ki-67 (MIB-1) and E-cadherin (36B5) antibodies. Quantitative assessments of the expression and descriptive statistical analyses were performed. RESULTS In 72.7% of the cases, clinically advanced stages III-IV were diagnosed. Average survival time was 56.09 months, and 72.7% of patients died as a consequence of the tumour. Immunoreactivity of p53 (>10% of cells) was detected in the 81.8% of the cases. The 72.7% of the cases showed overexpression of Ki-67 (>50% of cells). The cases with low immunoexpression of Ki-67 and p53 had the best clinicopathological data. All cases showed a decreased expression of E-cadherin. CONCLUSIONS BSCCL is an aggressive variant of the squamous cell carcinoma and has a high expression of p53 and Ki-67 with a low expression of Ecadherin. These results could be related to the aggressiveness of the disease and its poor prognosis.

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
BACKGROUND Basaloid squamous cell carcinoma (BSCC) is a distinct variant of squamous cell carcinoma that was first described by Wain et al in 1986. Since then, about 160 cases have been reported in the literature. Only 40 cases have been described in the larynx. METHODS Four cases of BSCC of the larynx treated in our department between 1986 and 2000 are presented. The clinical features, biological behavior, and histopathological and immunohistochemical characteristics of this uncommon tumor are described, and the relevant literature is reviewed. RESULTS The main clinical presentation did not differ from other histological types of laryngeal carcinoma. The clinical course, however, was much more aggressive. All the patients received aggressive therapy including radical surgery and radiation. Two patients received chemotherapy. Two of the 4 patients presented died of distant metastasis shortly after diagnosis and treatment. CONCLUSIONS The finding of this study with a limited number of patients supports previous reports suggesting that BSCC is a highly aggressive tumor that presents in older population with male predominance. The frequency of associated regional as well as distant metastases suggests that aggressive treatment is indicated and that systemic chemotherapy should be contemplated.

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
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
This report concerns a 46-year-old female who presented with 3 months of abdominal pain and underwent a right hemi-hepatectomy for a 27 x 25 x 15 cm, centrally necrotic tumor that showed histological, immunohistochemical and ultrastructural features typical of a basaloid squamous carcinoma (BSC). A primary tumor at another site was not diagnosed and she died of disease 2 years later after several intra-abdominal recurrences. The entity of BSC was first described in 1986 and is a rare, poorly differentiated variant of squamous cell carcinoma occurring in various sites including the upper aerodigestive tract, esophagus, lung, anus, cervix and thymus. It has never been reported arising in the liver. It has characteristic histological, immunohistochemical and ultrastructural features and is associated with a poor prognosis. Whilst no other primary tumor was diagnosed, it is not possible to substantiate that this is a primary hepatic tumor in the absence of an autopsy examination to exclude an occult malignancy in another site.

Abstract
Exophytic and papillary squamous cell carcinomas (SCCs) are uncommon variants of SCC of the upper aerodigestive tract mucosa. The histomorphologic distinction between these variants has not been previously attempted or correlated with prognostic outcome. One hundred four cases of exophytic and papillary SCCs of the larynx were identified in the files of the Armed Forces Institute of Pathology from 1971 to 1991. The patients included 25 women and 79 men, aged 27 to 89 years (average 60.7 years). Patients had hoarseness at presentation, and many patients were using tobacco (n = 87) and/or alcohol (n = 49). Tumors measured up to 6 cm in greatest dimension. The larger tumors were associated with vocal cord impairment (n = 39). Histologically, the SCCs were divided into 2 growth patterns: papillary-frond (n = 12) or broad-based, exophytic (n = 92). Patients were treated with excisional biopsy, vocal cord stripping, and/or laryngectomy, in conjunction with radiation therapy (n = 70). Eighty-seven patients had no evidence of disease at last follow-up (average follow-up 8.6 years). Seventeen patients with an exophytic pattern died with disease (10 disseminated disease; 7 local disease). No patients with papillary patterns died of disease, although there had been 4 recurrences. In conclusion, patients with papillary and exophytic SCCs have a better prognosis than those with conventional SCCs, and the prognosis for those with papillary SCCs is even better.

Abstract
AIM: To further clarify the clinicopathological, immunohistochemical and electron microscopic features, and prognostic aspect of basaloid squamous carcinoma (BSC), a rare esophageal carcinoma.
METHODS: We reviewed 763 documented cases of esophageal malignancies (1977-1996) from our hospital, and discovered 16 (2.1%) cases of BSC. The clinicopathological features of these cases were evaluated. Immunohistochemistry (S-P method), histochemical stains, and electron microscopy were used to further characterize the neoplasm.
RESULTS: The tumors were classified into stages I (n = 1), IIA (n = 6), IIB (n = 2), III (n = 5), and IV (n = 2) according to the criteria of the UICC TNM classification system of malignant tumors (1987). Most neoplasms were located in the mid third of the esophagus. Grossly, they had a similar appearance of conventional esophageal carcinoma, but showed a typical cytoarchitectural pattern of BSC histologically. The most important histologic feature of this tumor is carcinoma with a basaloid pattern, intimately associated with squamous cell carcinoma, dysplasia, or focal squamous differentiation. The basaloid cells were round to oval in shape with scant cytoplasm, arranged mainly in the form of solid, smooth-contoured lobules with peripheral palisading. A panel of immunostains were used for the basaloid component of the tumor with the following results: CK (Pan) 14/16 (+); EMA 16/16 (+); Vimentin 4/16 (+); S-100 protein 7/16 (+). CEA and smooth muscle actin were negative. Electron microscopy (EM) revealed that the basaloid cells were poorly differentiated, with a few desmosomes and fibrils, and numerous free and polyribosome. Of the 11 patients with adequate follow-up 8 died within 2 years, with an average survival time of 16.2 months. No stage II, III or IV cases survived beyond 5 years. The one-year survival rate was 60% and two-year 20%.
CONCLUSION: The BSC of esophagus is a distinct clinicopathological entity with poor prognosis. The cellular differentiation and biologic behavior of esophageal BSC were assumed to occupy a station intermediate between that of conventional squamous cell carcinoma and small undifferentiated cell carcinoma.

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
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
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
Basaloid-squamous carcinoma is a unique and infrequent variant of squamous cell carcinoma with a predilection for occurring in the upper aerodigestive tract. The cardinal diagnostic criteria are the presence of basaloid cells arranged in lobules or cords and a squamous component. Another feature that distinguishes basaloid-squamous carcinoma from conventional squamous cell carcinoma is the development of multiple foci of amorphous, eosinophilic, or mucinous materials among the basaloid tumor cells. It is this feature in basaloid-squamous carcinoma that causes confusion with adenoid cystic carcinoma, especially the solid variant of adenoid cystic carcinoma. To clarify the distinctive features of these two types of tumors, the ultrastructural findings in three basaloid-squamous carcinomas from the head and neck region were compared with three adenoid cystic carcinomas, one from the head and neck region and one each from trachea and bronchus. Widened intercellular spaces, tonofilaments, and replicated basal lamina were present in both types of tumor. However, the ultrastructural features of glandular differentiation were present only in adenoid cystic carcinoma, whereas the ultrastructural features of squamous cell differentiation were present only in basaloid-squamous carcinoma. The distinction between basaloid-squamous carcinoma and adenoid cystic carcinoma is important since basaloid-squamous carcinoma is a clinically aggressive, high-grade form of squamous cell carcinoma, generally with a worse prognosis than adenoid cystic carcinoma.
