[Steatocystoma multiplex].

A 50 years old male patient with numerous cysts over the scalp since the age of 48 is reported in whom the lesions appeared abruptly in two crops in a short period of time. Several biopsies were done showing most of them the typical histologic characteristics of steatocystoma multiplex. The authors remark in this patient the nonhereditary character of the condition, appearing late in life with an eruptive character and strict limitation over the scalp, features that are not often seen in steatocystoma multiplex. The authors pointed out that not all the cysts showed the typical histopathological picture of the disease. Therefore several biopsies must sometimes be done, before the diagnosis is established.
