UNLABELLED Trichogerminoma is a rare cutaneous adnexal neoplasm of the hair germ cell and usually associated with benign clinical course and favorable outcome. Since its first description by Sau et al. in 1992, only a few cases have been reported up to date. Herein, we report two additional cases occurring in the hip and right thigh, respectively. Both patients are male, one is 78 years old, th...

Basal cell carcinoma (BCC) and trichoepithelioma (TE) are sometimes diagnostic challenges for the pathologist in terms of their differential diagnosis. Although literature is quite rich in information about histologic and immunohistochemical clues to distinguish the differences between both, no single finding must be completely reliable. Moreover, some consider that TE is a better differentiate...

Accepted 21 May, 2003 Background: Basement membrane alterations are common in malignancies, and they may indicate tumoral aggressiveness. Distinct patterns of tumoral coverage by collagen IV were reported in nodular and aggressive basal-cell carcinomas (BCCs). Differential expressions of a (IV) collagen chains were also shown on frozen sections. The aim of our work was to document the immunohis...

Brooke-Spiegler syndrome is a rare entity. It is an autosomal dominant syndrome in which multiple trichoepitheliomas, cylindromas, or other adnexal tumors are seen. Very few cases of Brooke-Spiegler syndrome are reported in the literature. We came across a 40 -year-old female in which multiple trichoepitheliomas and cylindromas were seen on scalp. In view of clinical history and histopathologic...

AIMS Differential diagnosis between the group of trichoadenoma, trichofolliculoma, trichoepithelioma, trichoblastoma and basal cell carcinoma has been creating some difficulties for the pathologist and the clinicians, particularly in the presence of small specimens. MATERIAL AND METHODS A total of 30 cases of benign tumours of cutaneous appendages originating from the hair follicle and 30 cas...

BACKGROUND In addition to the well-defined histological criteria for squamous cell carcinoma (SCC) and basal cell carcinoma (BCC), immunohistochemical techniques can be used in difficult cases for their differentiation. As differential diagnosis between trichoepithelioma (TE) and BCC is sometimes difficult for the clinician and the pathologist, CD10 may be a useful marker for definite diagnosis...

Differential diagnosis of trichoepithelioma (TE) and basal cell carcinoma (BCC) on the basis of clinical symptoms and laboratory investigations may be difficult in certain patients. The aim of the present study was to compare cluster of differentiation 10 (CD10) and androgen receptor (AR) expression patterns in BCC and TE, to investigate the predictive power of these proteins as markers of the ...
