Linear trichoepithelioma on the neck of a 15-year-old girl
Abstract
Trichoepitheliomas are trichogenic tumors that can have various clinical morphologies. These tumors are benign and differentiate toward the outer root sheath of the hair follicle. Solitary trichoepitheliomas arise sporadically, in contrast to multiple trichoepitheliomas, which are usually inherited as an autosomal dominant trait or as part of various genetic syndromes. We report a case of an adolescent female with a linear array of trichoepitheliomas on her left neck.
