title: Pruritic bluish-black subcutaneous papules on the chest.
abstract: Steatocystoma multiplex (SM) is characterized by multiple dermal cysts involving the pilosebaceous glands. Although most presenting cases are sporadic, there is a rare familial syndrome involving a mutation in keratin 17 (K17) that is inherited in an autosomal dominant fashion. SM often presents concomitantly with eruptive vellus hair cysts (EHVS) and pachyonychia congenital type 2 (PC-2). We report a sporadic case of SM in a 21-year-old man.
