Solitary nasal trichoepithelioma.

Trichoepitheliomas are benign cutaneous neoplasms occurring mostly on the face, which derive from pillous follicles. There are two clinical presentations: a hereditary sex-linked multiple form that usually affects the face, scalp and upper thorax of young adults; and a non-hereditary solitary form that may affect any part of the body (but mostly the face) of adults. The diameter is rarely more than 2 to 3 cm.2 It is an extremely rare tumor; in the literature we surveyed, there were only two cases of trichoepitheliomas involving the skin in the nose area. This paper reports a case of a solitary nasal trichoepithelioma that was removed surgically, followed by a flap rotation. We discuss the diagnostic and therapeutic aspects of this rare skin tumor.
