Ulcerative giant solitary trichoepithelioma of scalp: a rare presentation
نویسندگان
چکیده
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 features are in contrast to the conventional trichoepithelioma, which presents as multiple small translucent circumscribed papules of 2–4 mm in diameter, in children and young adult on the face. To the best of our knowledge no case of ulcerative giant solitary trichoepithelioma on scalp has been reported previously.
