Abstract
ABSTRACT Basal cell carcinomas (BCCs) are common malignancies that usually show clear histomorphologic features, but in certain instances, it can display different patterns of differentiation leading to potential diagnostic confusion. BCCs with neuroendocrine differentiation/expression have been mentioned only briefly in the literature. In this study, we present cases of BCCs with neuroendocrine differentiation/expression that demonstrate reproducible histopathological features. Twenty-four cases were included in the study. All tumors showed conventional histopathologic features that are seen in BCCs, but in addition, all the tumors showed large, hyperchromatic, pleomorphic, mononuclear, and multinucleate cells with intracytoplasmic inclusions and intranuclear cytoplasmic invaginations, with rare cases showing stippled nuclei (salt-and-pepper appearance). These histologic features were somewhat concerning for a neuroendocrine carcinoma; thus, immunohistochemistry studies were performed in all cases at the time of diagnosis. By immunohistochemistry, all tumors showed expression of neuroendocrine markers. CD56 was expressed in all cases 24/24, chromogranin was positive in 17/24 cases, and synaptophysin 8/24 was positive in cases. This study confirms a subset of histopathologic features that are present in cases of BCC that are associated with neuroendocrine expression that can potentially be interpreted differently and can create a diagnostic pitfall. Neuroendocrine expression in BCCs is yet uncertain, and further studies are required to fully understand this phenomenon. To avoid diagnostic pitfalls, dermatopathologists must be aware of these unusual histopathologic features and aberrant immunostaining in such tumors; hence, it is advised to perform a thorough histologic inspection.

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

Abstract
Basal cell carcinoma (BCC) is the most common type of malignant tumor in the periocular region. BCCs with neuroendocrine differentiation in the periocular region, however, have not been described in the literature.We present a retrospective case review of a patient with an eyelid BCC with neuroendocrine differentiation. Demographical, clinical, radiological, surgical, histological, and follow-up data are presented.The patient presented with a slow-growing lesion of the eyelid with associated epiphora and dull ache. Initial incisional biopsy of the lesion revealed an infiltrating carcinoma composed of epithelial cells. Immunohistochemistry showed that the tumor was positive for p40, Ber-Ep4, neuron specific enolase (NSE), chromogranin A, CD56 (NCAM), and synaptophysin. The pathology from the margin-controlled excision showed basosquamous cell carcinoma with neuroendocrine differentiation. Tumor recurrence was not detected clinically at the post-operative six-month review.BCC with neuroendocrine marker positivity represents an important diagnostic differential for rare eyelid carcinomas such as primary cutaneous neuroendocrine carcinoma and metastatic small cell carcinoma that have a poor prognosis. The prognostic importance of neuroendocrine marker positivity in BCCs is uncertain. The present case provides further evidence for neuroendocrine differentiation in BCCs.

Abstract
In the skin and breast, endocrine tumors are composed of a heterogeneous mixture of endocrine and exocrine cells. The definition of "pure" endocrine carcinomas is a matter for debate, and as a consequence, there is lack of uniform diagnostic criteria. There are no significant clinical differences in either overall or disease-free survival between matched neoplasms with endocrine and without endocrine differentiation nor between the degree of endocrine differentiation and tumor size, stage, or prevalence of vascular invasion for both sites (skin and breast). Here, endocrine tumors of the skin and breast are grouped respectively into three categories that include most of the neuroendocrine tumors of the skin and breast as seen in routine practice. It was felt that the number of different types of neuroendocrine tumors is so conspicuous that it is impossible to organize them in an orderly classification. It has been proposed therefore, for practical diagnostic routine purposes, to arrange these neoplasms into a working formulation. The latter includes heterogeneous lesions respectively of the skin and breast within the same group that have clinical features in common.

Abstract
PURPOSE This review provides a description of the epidemiology and survival outcomes for cases with metastatic basal cell carcinoma (mBCC) based on published reports (1981-2011). METHODS A literature search (MEDLINE via PubMed) was conducted for mBCC case reports published in English: 1981-2011. There were 172 cases that met the following criteria: primary BCC located on skin, metastasis confirmed by pathology and metastasis not resulting from direct tumour spread. From these, 100 mBCC cases with explicit information on follow-up time were selected for analysis. Survival analysis was conducted using Kaplan-Meier methods. RESULTS Among 100 mBCC cases selected for analysis, including one case with Gorlin syndrome, 50% had regional metastases (RM) and 50% had distant metastases (DM). Cases with DM were younger at mBCC diagnosis (mean age, 58.0 versus 66.3 years for RM; P=0.0013). Among 93 (of 100) cases with treatment information for metastatic disease, more DM cases received chemotherapy (36.2% versus 6.5% for RM), but more RM cases underwent surgery (87.0% versus 40.4% for DM). Among all 100 cases, median survival after mBCC diagnosis was 54 months (95% confidence interval (CI), 24-72), with shorter survival in DM (24 months; 95% CI, 12-35) versus RM cases (87 months; 95% CI, 63-not evaluable). CONCLUSION Cases with RM and DM mBCC may have different clinical courses and outcomes. Based on published reports, DM cases were younger at mBCC diagnosis, with shorter median survival than RM cases. This study provides a historical context for emerging mBCC treatments.

Abstract
INTRODUCTION Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome, is an autosomal dominant inherited disorder which is characterized by the presence of multiple basal cell carcinomas, maxillary keratocysts, and musculoskeletal anomalies. CASE REPORT We present a case of a patient suffering from Gorlin-Goltz syndrome who developed an intraosseous basal cell carcinoma associated with a recurrent maxillary keratocyst. To our knowledge, this is the first case of malignant transformation of a keratocyst into a basal cell carcinoma described in the literature. CONCLUSION This case highlights the importance of careful histologic examination of keratocysts excised in patients suffering from Gorlin-Goltz syndrome.

Abstract
Uncommon histologic variants of basal cell carcinoma (BCC) can present a diagnostic challenge. In this case series, we describe 3 patients with unusual BCCs encountered in a dermatologic surgical unit over a 1-year period from September 2003 to September 2004. The formalin-fixed, paraffin-embedded histologic specimens were initially examined microscopically after staining with hematoxylin and eosin. Additional stains, including diastase periodic acid-Schiff, colloidal iron, carcinoembryonic antigen, and cytokeratin-20, were subsequently performed as appropriate. Of the 3 lesions, one exhibited apocrine differentiation and two demonstrated a trabecular growth pattern. Although BCCs demonstrating apocrine differentiation have previously been described, a trabecular growth pattern, to our knowledge, has not been previously reported for BCC.

Abstract
Although commonly used in the treatment of melanoma, sentinel lymph node biopsy has not yet been successfully used to detect lymphatic metastasis of basal cell carcinoma because of exceedingly low rates of metastasis. We describe the use of lymphatic mapping and sentinel lymph node biopsy in a patient after basal cell carcinoma was identified within a lymphatic vessel in the primary excisional specimen. As a result, the patient was found to have clusters of basal cell carcinoma in a sentinel lymph node resected from the right deltopectoral groove. Although metastatic basal cell carcinoma is exceedingly rare, we conclude that sentinel lymph node biopsy may be useful for certain high-risk lesions, such as lesions demonstrating histologic evidence of lymphatic invasion. Further experience is necessary to determine the clinical usefulness of sentinel node biopsy in these patients and its effect on patient survival.

Abstract
BACKGROUND Distinguishing merkel cell carcinoma (MCC), small cell lung carcinoma (SCLC) metastatic to the skin, and atypical basal cell carcinoma (BCC) can be problematic in some cases. Significant differences in the biology of these tumors necessitate that they need to be distinguished from one another. METHODS We evaluated the immunophenotypic characteristics of 22 MCCs, nine SCLCs, and 19 BCCs using antibodies to cytokeratin 20 (CK20), thyroid transcription factor-1 (TTF-1), CD117, and DNA topoisomerase II-alpha (topo II). RESULTS Nineteen of 22 MCCs stained with the antibody to CK20, none stained with anti-TTF-1, and 13 stained with anti-CD117. No SCLC stained with anti-CK20, all stained with anti-TTF-1, and eight stained with anti-CD117. No BCC stained with any of the three markers. The proliferative index (PI), determined by the expression of topo II, was similar for SLCLs (mean 58.5 +/- 9.0%) and MCCs (mean 45.2 +/- 12.4%) and was lowest in BCCs (mean 25.0 +/- 8.7%). CONCLUSIONS CK20 and TTF-1 appear to be reliable in distinguishing MCC from SCLC. CD117 is expressed in both MCC and SCLC, limiting its diagnostic utility. CK20, TTF-1, and CD117 are not expressed in BCC. The high PI seen in MCCs suggests a role for topoisomerase II inhibitors in their treatment.

Abstract
Diagnostic records of 30 primary and one metastatic follicular stem cell carcinomas in 30 dogs were reviewed. Neoplastic cells had a clear cytoplasm and formed lobules and nests surrounded by a basement membrane. Trichoepitheliomatous and apocrine differentiations were noted in 22 of 30 (73%) and 21 of 30 (70%) primary tumors, respectively. Glycogen was present in 20 of 20 (100%) tumors tested, suggesting tricholemmal differentiation. Antibodies against AE1/AE3 cytokeratin, vimentin, and melanA/MART1 stained 29 of 30 (97%), 29 of 30 (97%), and 12 of 27 (44%) primary tumors, respectively. Small amounts of melanin were identified in 14 primary tumors, either on the hematoxylin and eosin-stained section (n = 6), or on the Fontana-stained section (n = 8 of 14). Ultrastructural features of neoplastic cells included cell junction complexes, swollen mitochondria, neuroendocrine-like granules, and intracytoplasmic non-membrane-bound accumulation of proteinaceous material. Features of this neoplasm are consistent with a follicular stem cell origin. Follow-up information was available for eight dogs. Metastases developed in the draining lymph node at the time of excision of the primary tumor (n = 1) or subsequently (n = 3).
