Desmoplastic Trichoepithelioma: Histopathologic and Immunohistochemical Criteria for Differentiation of a Rare Benign Hair Follicle Tumor From Other Cutaneous Adnexal Tumors

<p class="abstract"><span lang="EN-US">Trichoepithelioma a small benign tumor derived from basal cells in the hair follicle. A trichoepithelioma can undergo malignant transformation into the basal cell carcinoma. The recognition of trichoepithelioma is important because of its close resemblance to basal cell carcinoma and other skin adnexal tumors, both clinically and histopathologically. Here we present case of 40 year old male presenting with painless swelling in right thigh. Wide excision of swelling was done and sent for histopathology which showed the swelling to be trichoepithelioma.</span></p>

Adnexal Tumour

Trichoepithelioma is a benign, cutaneous neoplasm originating from the hair follicle and is categorized into singular trichoepithelioma, multiple trichoepithelioma and desmoplastic trichoepithelioma wherein desmoplastic trichoepithelioma is cogitated as an exceptional, cutaneous adnexal tumour. Desmoplastic trichoepithelioma was initially scripted by Hartzell in 1904 wherein the lesion was described as a benign, cystic epithelioma. Desmoplastic trichoepithelioma can be additionally nomenclated as epithelioma adenoides cysticum, morphea - like epithelioma or sclerosing epithelial hamartoma 1. Familial instances of desmoplastic trichoepithelioma are infrequent and can be misdiagnosed on account of adjunctive benign, cutaneous, adnexal neoplasms depicting subtle clinical features, excepting a nodular basal cell carcinoma. Cogent clinical and histological features can assist the diagnosis of desmoplastic trichoepithelioma 1, 2.
