Abstract
Cutaneous carcinosarcoma (CCS) is a rare non-melanoma skin cancer with a biphasic growth pattern. A tumour is composed of epithelial and mesenchymal cells that show clonality. In most cases, CCS develops in the head-and-neck region on the chronic sun-exposed skin of males. Here, we describe an 80-year-old female patient who developed a giant, pendulous CCS on the leg. A tumour was surgically removed. We found no evidence of metastatic spread.

Abstract
Basosquamous carcinoma is a rare cutaneous tumor considered by some authors as an aggressive type of basal cell carcinoma having a propensity for local recurrence and a potential risk for regional and distant metastatic spread. Herein we present 2 cases of basosquamous carcinoma of head and neck region, with metastatic spread to parotid gland (case 1) and to cervical nodes (case 2). Both patients had recurrence 2 years after initial treatment of the primary lesion (first patient: surgery; second patient: radiotherapy) and at the same time developed regional metastases. We conclude that basosquamous carcinoma must be considered as an aggressive variant of basal cell carcinoma having a great propensity to metastasize even at an early tumor stage. The clinical features, the morphologic aspects, and the treatment of this rare entity are discussed in this article.

Abstract
OBJECTIVES: Basosquamous carcinoma (BSC) is a rare tumor entity, and the most common onset is in the head and neck region (BSC-HN). The data on diagnosis, treatment, and especially risk assessment concerning disease course and outcome are deficient or inconsistent. This study aimed to evaluate risk factors for local relapse (LR) and lymph node metastasis (LNM) and their impact on progression-free survival (PFS). MATERIALS AND METHODS: In a retrospective monocentric study, patients with BSC-HN treated between 1999 and 2011 were analyzed regarding clinical and histologic characteristics. Prognostic parameters for LR, LNM, and PFS were evaluated. In total, 89 patients (55 male, 34 female, mean age of 71.8 years) with a mean follow-up time of 47.7 months (range 12-112) were included. RESULTS: LR occurred in four patients (4.5%), LNM occurred in five patients (5.6%). Patients with LNM had a significantly shorter PFS time (16.1 months) compared with patients without LNM (154.2 months; P < .001). Tumor depth and size (T classification), incomplete resection, localization at the ear, deep maximal vertical infiltration, muscle and vessel invasion all showed significant (P < .05) associations with LR, LNM, and shorter PFS time. BSC showed more histologic features of basal cell carcinoma (BCC), especially with regard to BerEP4 expression. CONCLUSION: While histology shows some typical characteristics of BCC, the biologic behavior and aggressiveness of BSC are similar to those of cutaneous squamous cell carcinoma. This is the first study to show that LR and, especially, LNM indicate a higher risk of an unfavorable outcome.

Abstract
Metatypical basal cell carcinoma (MTBCC) represents a high-risk type of cutaneous tumour. We report about three different patients with relapsing advanced large MTBCC: one of the scalp and two of the cheek region. Such patients required in most of the cases a complex surgical approach to achieve a stable and complete remission. In the first presented patient a combination of flaps and grafts has been performed. We describe tailored surgical approaches. By this contrivance it is possible to treat even elderly patients with exposed bone after complete excision effectively and safe. Interdisciplinary team work is for the benefit of these patients.

Abstract
Context.—Basaloid squamous cell carcinoma (bSCC) is an uncommon variant of squamous cell carcinoma, which may overlap histologically with basal cell carcinoma with squamous metaplasia (BCCm).
Objective.—To aid in the differentiation of these neoplasms using immunohistochemical staining because of the worse prognosis associated with bSCC.
Design.—Using immunohistochemical techniques, we investigated BerEp4, cytokeratin 17 (CK17), and cytokeratin 14 (CK14) protein expression in 25 cases of bSCC (8 cutaneous [32%], 12 aerodigestive tract [48%], and 5 lymph node metastases [20%]) and 43 cases of BCCm (39 cutaneous [91%], and 4 metastases [9%]). An immunoreactivity score was assigned using the percentage of tumor cells staining and the pattern of expression. Interobserver agreement for 2 independent pathologists was assessed using a κ coefficient.
Results.—The mean percentage of staining was significantly higher in BCCm, compared with bSCC (BerEp4, P = .006; CK17, P < .001; CK14, P < .001; unpaired t test), with 58% of BCCm cases (25 of 43) displaying diffuse staining for all markers, and nearly all (98%; 42 of 43) displaying diffuse staining for CK17 and CK14. In contrast, no bSCC cases (0%) displayed diffuse staining for all 3 markers, and only 8% (2 of 25) displayed diffuse staining for CK17 and CK14. High interobserver agreement was determined.
Conclusions.—BerEp4 alone is unreliable for differentiation between BCCm and bSCC, and the addition of either CK14 or CK17 will augment the sensitivity and negative predictive value of BerEp4 staining in BCCm and bSCC diagnosis.

Abstract
BACKGROUND The morpheaform subtype of basal cell carcinoma (BCC) often presents a diagnostic histological challenge, and its true margin may be difficult to determine with accuracy. This tumor may also be difficult to distinguish from other adnexal neoplasms having a benign clinical course. Previous work has shown that cytokeratin 17 (CK17 or K17) expression is high in BCC. OBJECTIVE To confirm the expression of K17 across the subtypes of superficial, nodular and morpheaform BCC variants and to compare K17 expression in each of these subtypes of BCC with that in two other adnexal neoplasms. METHODS Tissue specimens from each tumor category were randomly collected, immunolabeled, and scored for K17 expression according to intensity and extent of immunostaining. RESULTS Our results indicate that K17 is a useful marker in the identification and outlining of BCC. Moreover, in morpheaform BCC, K17 immunostaining clearly detected individual tumor cells well away from the dermal tumor strands that otherwise seemed nonmalignant according to hematoxylin and eosin staining alone. In addition, the expression of K17 in morpheaform BCC is capable (100% of specimens; p < .001) of distinguishing this tumor from desmoplastic trichoepithelioma. CONCLUSION We propose that K17 immunostaining could improve the diagnostic and surgical management of these tumors.

Abstract
BACKGROUND Basosquamous carcinoma is considered an aggressive type of basal cell carcinoma (BCC) with an increased risk of recurrence and metastases. This concept has been perpetuated in the literature in spite of confusing terminology, limited scientific data, and the contradictory surgical experiences of some observers. METHODS This is a narrative review based on a MEDLINE search of articles in English and a manual search of popular dermatology textbooks to define basosquamous carcinoma, its incidence, clinical behavior, and treatment of choice. RESULTS There are no specific clinical features to distinguish basosquamous carcinoma from other BCC types and the diagnosis is made only after biopsy. There are several histologic definitions of basosquamous carcinoma ranging from a characteristic combination of BCC and squamous cell carcinoma with or without a transition zone, to any BCC with evidence of keratinization. The authors confine the use of the term to an infiltrative growth BCC with areas of keratinization and/or intercellular bridge formation in the setting of a prototypic proliferative stromal reaction. The term "metatypical basal cell carcinoma" is considered a synonym but its use is discouraged for the reasons outlined. The reported incidence of basosquamous carcinoma ranges from 1.2% to 2.7%. Published recurrence rates are 12% to 51% for surgical excision and 4% for Mohs micrographic surgery. The incidence of metastasis is at least 5%. The aggressive biological behavior and clinical course distinguish basosquamous carcinoma from other forms of BCC. LIMITATIONS This study is a literature review, contains a limited number of patients, and is mostly retrospective studies. CONCLUSION The terminology surrounding basosquamous carcinoma is confusing and there is a need for more uniform language. Based on our review and personal experience, we propose a more precise and specific definition. Data regarding the incidence, recurrence, and metastasis rates of basosquamous carcinoma are based mostly on retrospective series with a limited number of cases. We conclude that although the incidence of basosquamous carcinoma is unknown, there is a literature precedent suggesting more aggressive biological behavior. We believe that complete surgical excision is the preferred approach, and that basosquamous carcinoma is an ideal candidate lesion for Mohs micrographic surgery.

Abstract
Background Metatypical cell carcinoma can be considered as a new entity of skin cancer, being an intermediate typology between basal cell carcinomas and squamous cell carcinomas. The behaviour of the metatypical cell carcinoma lies between these two varieties of skin cancer. It is difficult to perform a differential diagnosis based on morphological and clinical features – therefore it is only possible by accurate histology. Methods The authors have retrospectively analysed clinical records of 240 patients who were affected by metatypical skin cancer and who were treated by surgery, radiotherapy and chemotherapy. Results MTC affected more males than females (62.5% vs 37.5%) than males. The most affected site was the cervicofacial area, 71.7%; then the trunk, 10%; the limbs, 9.6%; the scalp 3.7%; and other regions 5%. A recurrence occurred in 24 cases (10%), mainly in head and neck area. Conclusion In this manuscript, the authors have emphasised the importance of conducting a differential diagnosis, and the importance of the specific treatment for metatypical skin cancer, even though more clinical studies and long-term follow-ups are required before establishing specific guidelines.

Abstract
Recent insights into the cell biology of the epidermis and its appendages are transforming our understanding of the pathogenesis of basal cell carcinoma (BCC). The significant progress that has been made warrants a comprehensive review of the molecular and cellular pathology of BCC. The items addressed include environmental and genetic risk factors, the biology of the putative precursor cell(s), and the contribution of aberrations in processes such as apoptosis, cell proliferation, differentiation and signalling to carcinogenesis. Furthermore, established and novel treatment modalities are discussed with particular attention to future biological approaches.

Abstract
AIMS Seventy-five skin tumours were studied to investigate the value of immunohistochemistry in differentiating basal cell, squamous cell and basosquamous carcinomas of the skin. METHODS AND RESULTS Archived paraffin-embedded tissue samples of basal cell carcinomas (n = 39), squamous cell carcinomas (n = 23) and basosquamous carcinomas (n = 13) were stained immunohistochemically using a panel of antibodies. All of the basal cell carcinomas stained positively for Ber EP4, in contrast to the group of squamous cell carcinomas, that showed no staining. Basosquamous carcinomas all showed at least some areas of Ber EP4 positivity. None of the basal cell carcinomas, but most of the squamous cell carcinomas (22 of 23) expressed epithelial membrane antigen (EMA). Only one of the basosquamous carcinomas expressed EMA positivity focally. CAM 5.2, carcinoembryonic antigen (CEA) and 34betaE12 antibodies lacked specificity in relation to the different tumour types. CONCLUSION Distinction of basal and squamous cell carcinomas of the skin can be readily achieved with routine immunohistochemistry using Ber EP4 and EMA. Identification of basosquamous carcinoma is also facilitated with this method.

Abstract
A case of basal cell carcinoma with giant cells of the central epithelial and surrounding stromal components is presented. The lesion was an 8-mm dome-shaped papule on the ear of a 66-year-old man. The giant cells of the epithelial component shared the immunophenotype of the more typical cells of the basal cell carcinoma (keratin, smooth muscle actin, and bcl-2 positive), whereas the stromal giant cells were positive only for bcl-2. This case represents a peculiar variant of pleomorphic basal cell carcinoma, the significance of which is unknown.
