Steatocystoma Multiplex with Embryonal Hair Formation

Abstract

Steatocystoma multiplex is a relatively rare condition characterized by the formation of multiple cutaneous sebaceous cysts. The first authentic case was described by Bosellini¹in 1898. Since then many cases have been reported in the European and American literature.^2-23It is our purpose to report three of the cases seen by us, and to give some consideration to the pathogenesis, on the basis of findings in these cases. Report of Cases Case1.—An 18-year-old Chinese boy was seen on July 30, 1956. His condition started 18 months previously. The lesions were localized to the chest and abdomen, and did not give rise to any symptoms. The patient's chest and abdomen were covered by numerous rounded papules symmetrically distributed, ranging in size from that of a pinhead to that of a split pea, somewhat indurated, nontender, adherent to the overlying skin and movable with it.
