Steatocystoma multiplex is a rare condition that is characterized by cutaneous cysts and may be inherited in an autosomal dominant manner or may occur sporadically. The pathogenesis is hypothesized to involve mutations in the keratin 17 gene. There are no internal manifestations. The lesions are usually asymptomatic. However, a suppurative variant exists in which the lesions become inflamed and suppurative after minor trauma. Treatments include cryosurgery, aspiration, surgical excision, laser therapy, and modified surgical incision techniques. This report presents a case of steatocystoma multiplex, the suppurative variant, in a 26-year-old woman with involvement of rare locations on the buttocks, groin, and extremities.
