S Oshinsky, S Baum, M Huszar, A Debby, A Barzilai
AIMS: An increased prevalence of aggressive histological subtypes, such as the micronodular and morpheaform, has been seen, irrespective of the clinical course, in basal cell carcinoma (BCC) following irradiation for tinea capitis. The aim of this study was to assess the histopathological features of BCCs among patients irradiated for tinea capitis and correlate them with the clinical course. METHODS AND RESULTS: The medical records and BCC biopsy specimens of individuals who were previously irradiated for tinea capitis were revised...

Introduction: Recurrence rates for incompletely excised basal cell carcinoma (BCC) vary widely in the literature. Clinical observation is a commonly accepted method of follow up, however such management of these lesions still remains controversial. Aim: To evaluate the rate and factors associated with the recurrence of BCC of the head and neck region after incomplete excision. Material and methods: Medical records of 135 patients with 156 incompletely excised BCCs of the head and neck region were analyzed retrospectively...

Microcystic adnexal carcinoma (MAC) is a rare, slow-growing, infiltrative malignant tumour most commonly found on the head and neck. It often presents as a solitary skin-coloured or yellow papule, plaque or nodule. Ultraviolet radiation, immunosuppression and ionising radiation are possible risk factors. Clinical and histological differential diagnoses include morpheaform basal cell carcinoma and desmoplastic trichoepithelioma. The diagnosis is usually made by skin biopsy, and the characteristic features are small keratin-filled cysts with nests and cords which resemble ductal structures...

Basal cell carcinoma (BCC) is the most common cutaneous malignancy and is characterized by a high cure rate after local excision. Metastatic BCC (mBCC) is an exceedingly rare event, associated with poor prognosis. We report clinicopathological and immunohistochemical features of 15 mBCC metastatic to the thorax and bone. The patients were 14 males and one female with a mean age at diagnosis of cutaneous BCC of 53 years and at metastasis of 64 years. Primary BCC were primarily located in the head and neck or torso and microscopically included five nodular, three basosquamous, three mixed, and one each of superficial, infiltrative, micronodular, and morpheaform types...

Basal cell carcinoma (BCC) is a common, locally invasive epithelial malignancy of skin and its appendages. Every year, close to 10 million people get diagnosed with BCC worldwide. While the histology of this lesion is mostly predictable, some of the rare histological variants such as cystic, adenoid, morpheaform, infundibulocystic, pigmented and miscellaneous variants (clear-cell, signet ring cell, granular, giant cell, adamantanoid, schwannoid) are even rarer, accounting for <10% of all BCC's. Adenoid BCC (ADBCC) is a very rare histopathological variant with reported incidence of only approximately 1...

BACKGROUND: Morpheaform basal cell carcinoma (BCC) is a variant of BCC characterized by narrow strands and nests of basaloid cells with dense sclerotic stroma. The histologic extent often exceeds the clinical impression, leading to high recurrence rates after standard excision. The authors encountered a case with single-cell invasion distant from the main tumor. To date a systematic review of single-cell infiltration in morpheaform BCC has yet to be performed. DESIGN: Ten morpheaform BCCs, 10 nonmorpheaform aggressive BCCs, 5 desmoplastic trichoepitheliomas, and 2 microcystic adnexal carcinomas were identified by database search and confirmed on hematoxylin and eosin...

BACKGROUND: Ultraviolet radiation plays an important role in the pathogenesis of non-melanoma skin cancer. Outdoor workers, including farmers, experience higher exposure levels compared to the general population. Available literature data suggest that occupational ultraviolet exposure represents an independent risk factor for squamous cell carcinoma; whereas for basal cell carcinoma (BCC) this association still remains unclarified. OBJECTIVES: To analyse the epidemiological, clinical and histological data of patients diagnosed with BCC, and correlate them with outdoor occupation in farmers...

Desmoplastic trichoepithelioma (DTE) is a rare benign adnexal tumor with the characteristic features of asymptomatic, solitary, annular, indurated and centrally depressed papules or plaques, most commonly occurring in younger individuals on the face. Microscopically and clinically, DTE may be difficult to distinguish from other cutaneous adnexal neoplasms, particularly syringoma, cutaneous metastatic breast cancer, morpheaform basal cell carcinoma and microcystic adnexal carcinoma. The present study reports three cases of DTE...

BACKGROUND: The incidence of basal cell carcinoma (BCC) is rising and BCC treatment has an important impact on healthcare budget. Mohs micrographic surgery (MMS) has the highest 5-year cure rate but is an expensive technique. OBJECTIVES: To study the indication criteria for MMS, using a series of 1062 patients treated for facial BCCs between 1998 and 2011. METHODS: The accuracy of the indication criteria was evaluated by comparing the characteristics of BCC requiring one vs...

The eyelids represent a frequent site for numerous malignant tumors, which generally present subtle symptoms or can imitate benignant tumors. Our study was carried on 80 patients, 48 males and 32 females aged between 48 and 92 years. The patients were hospitalized in the Ophthalmology Clinic of the Emergency County Hospital of Craiova, Romania. The study was conducted over five years, between 2010 and 2014. Our study included 80 basal cell carcinomas of the eyelids, of which 48 (60%) were nodular basal cell carcinomas, 15 (18...

BACKGROUND: Desmoplastic trichoepithelioma (DTE), morpheaform basal cell carcinoma (BCC) and microcystic adnexal carcinoma (MAC) are sclerosing adnexal neoplasms with overlapping histopathologic features. We compared cytokeratin 15, (CK15), T-cell death-associated gene 51 (TDAG51), cytokeratin 20 (CK20) and androgen receptor (AR) in differentiating these tumors and assessed their expression in BCC subtypes. METHODS: Fifteen DTE, 15 infundibulocystic BCC, 18 micronodular BCC, 18 morpheaform BCC and 6 MAC were assessed for CK15, TDAG51, CK20 and AR expression...

Basal-cell carcinomas may show irregular, asymmetric subclinical growth. This study analyzed the efficacy of 'breadloaf' microscopy (serial sectioning) and three-dimensional (3D) microscopy in detecting positive tumor margins. Two hundred eighty-three (283) tumors (51.2%) were put into the breadloaf microscopy group; 270 tumors (48.8%) into the 3D microscopy group. The position of any detected tumor outgrowths was identified in clock face fashion. The time required for cutting and embedding the specimens and the examination of the microscopic slides was measured...

Although, generally BCC growths slowly and is minimally invasive, tumors developed in the head and neck region behave more aggressively with deep tissue invasion, recurrence and even local or distant metastases, causing significant morbidity or mortality. Recently, numerous studies have been conducted in order to identify new prognostic markers of BCC aggressiveness, but the results are not consistent. Thus, we were interested here in the immunohistochemical investigation of p53, D2-40 and α-SMA expression in the aggressive forms (eight infiltrative-morpheaform, six micronodular and six metatypical cases) versus superficial facial BCCs (five cases)...

BACKGROUND: On pathology review, basal cell carcinomas (BCCs) on the ear more commonly present as aggressive subtypes. It is unclear if this histologic observation translates into more clinically aggressive tumors. OBJECTIVE: We sought to determine the clinical aggressiveness of ear BCCs compared with BCCs elsewhere on the head and neck. METHODS: We conducted a retrospective chart review of all BCCs treated at an academic center from 2005 through 2012...
