TLDR Steatocystoma multiplex is a skin condition starting around age 26, linked to hair follicles, and related to eruptive vellus hair cysts.
The study evaluated 64 cases of Steatocystoma multiplex (SM), revealing that most cases were sporadic with an average onset age of 26 years, primarily affecting the arms, chest, axillae, and neck. All cases showed an eosinophilic cuticle and absence of a granular layer, with 17-42% displaying vellus hair, hair follicles, keratin, and smooth muscle components. The findings supported the hypothesis that SM is a hamartomatous condition and suggested that SM and eruptive vellus hair cyst (EVHC) are variants of a single disorder originating in the pilosebaceous duct.
