[Tricho-epithelioma multiplex: two cases reports]

Tricho-epitheliomas are benign tumors of the pilosebaccous apparatus. Multiple tricho-epithelioma form is particular. We report 2 new cases. 1) R.A., a 41 year-man with a 2 years history of histologically confirmed multiple tricho-epitheliomas. New lesions appeared during a 9 years-follow-up. Treatment was local excision of tumors. 2) M.B., a 41 year-man, have a 8 years history of 3 to 30 mm papulonodular lesions with telangiectasia, located on the face and associated to multiple milia, comedones and alopecia areata plaques. Histological study confirmed the diagnosis of multiple tricho-epitheliomas. Multiple tricho-epitheliomas is a genodermatosis it is often associated to other benign cutaneous tumors, mainly cylindromas and spiradenomas. It occurs in the 1st and 2nd decade. The lesions are symmetrically located on the face. Histological examination confirm the diagnosis. After repeated episodes, the lesions stabilize. Malignant changes are rare. Treatment is supported by aesthetic considerations. Various therapeutic means are available. Our reported cases are particular by the occurrence at relatively advanced age, the localization and the large size of some lesions. The associated alopecia areata in the 2nd patient could be fortuitous.
