Trichoepithelioma is a trichogenic tumor which arises from the inferior segment of hair follicle epithelium as hamartoma. Giant solitary trichoepithelioma is a distinct variant of trichoepithelioma. It has been defined as a solitary trichoepithelioma with a diameter greater than 2 cm [1]. It arises in elderly individuals and occurs mostly on the face, thigh and peri-anal region [2,3]. These fea...

Patients with the autosomal-dominant form of multiple familial trichoepithelioma develop numerous tumours on the face, neck and upper trunk, beginning in childhood. Malignant transformation of such lesions is quite rare; only one case of "malignant trichoepithelioma" has been reported previously, inferring pilomatrix carcinoma on a histological observation. We report here the case of a patient ...

Trichoepithelioma is a benign neoplasm that primarily shows follicular germinative differentiation. Classic trichoepithelioma typically presents as a skin-colored papule or nodule on the face or upper trunk; lesions have a predilection for the nose. Trichoepithelioma can be sporadic or familial and solitary or multiple. Most previously reported multiple trichoepithelioma cases are familial, and...

Trichoepithelioma (TE) is a benign skin neoplasm derived from the hair follicle. It is commonly located on the face and hairy skin. Malignant transformation is quite rare. TE affects adults and more frequently women. The most common presentations are noted in the 4th decade [1]. There are three variants of TE: solitary TE, multiple TE and desmoplastic TE [2-4]. The solitary TE is non-familial. ...

Trichoepithelioma is a rare benign skin lesion that originates from hair follicles. Trichoepitheliomas are mostly seen in the scalp, nose, forehead, and upper lip. We present a large family of Iranian origin with 15 individuals affected with multiple familial trichoepithelioma in four generations, and treated with three different methods. Trichoepithelioma is histologically similar to basal cel...

Trichoepithelioma is a well-recognized hamartoma of hair germ clinically presenting as solitary or multiple papules. Uncommonly, it may present as a large solitary lesion, termed as giant solitary trichoepithelioma (GST). A 50-year old man presented with a large, pedunculated mass over the root of nose obstructing visual field. It was excised and sent for histopathological examination. H&E stai...

Trichoepithelioma is an uncommon, benign hamartomatous tumor of the pilosebaceous follicle. Presenting as multiple papules and nodules on face and neck, they pose a significant cosmetic problem in affected individuals. Familial involvement of this dermatosis occurs in an autosomal dominant pattern, the locus being located on chromosome 9p21, which causes multiple facial lesions in family member...
