[Acne-like eruption induced by pseudo-xanthoma elasticum (author's transl)]

Pseudoxanthoma elasticum can induce acne-like eruption. The lesions are located on the latero-cervical parts and consist of comedones, cysts and inflammatory nodules. Histologically, there are no transepithelial eliminations or follicultitis, but a very important granulomatosus tissue with epithelioid cells and a giganto-cellular reaction with elastotic fibres phagocytosis. These findings are different from the cases with association of P.X.E. and elastosis perforans, but they are closely related to it. We think that these features are of a very great interest for the dermatological practice.
