A case of solitary trichodiscoma

Abstract

Trichodiscoma is a small benign fibrovascular tumor of the dermal part of the hair disc, haarscheibes. Trichodiscomas are found as asymptomatic skin-colored papules, 1-3 mm in diameter, usually on the face, upper part of the trunk and sometimes the extremities. Histopathologically, a sharply defined fibrovascular lesion with myxoid stroma is related with an adjacent hair follicle. In cases reported thus far, there have been multiple lesion, with some reports demonstrating transmission on a dominantly inherited basis. We present here a case of solitary trichodiscoma involving a patient with no familial involvement.
