Giant solitary trichoepithelioma: A rare trichogenic tumor

Abstract

Giant solitary trichoepithelioma (GST) is a rare benign skin adnexal tumor which arises from hair follicle. It represents more mature end of the spectrum of trichoblastoma, and a unique type of trichoepithelioma that is most common in elderly but can be present at any age. Only few cases are reported worldwide and some of which have showed malignant transformation in to basal cell carcinoma. This case is presented due to its scarce presentation over neck region and difficulty encountered in diagnosis of the case.
