Steatocystoma multiplex

    Clinical Features:

    • Steatocystoma simplex: solitary, sporadically occurring cyst
    • Steatocystoma multiplex: multiple cysts occurring as an autosomal dominantly inherited condition
    • Small white or yellow lesions, most commonly on the trunk, axillae, groin, head or neck
    • Often appear at puberty.

    Histologic Features:

    • Thin-walled cyst lined by squamous epithelium
    • The lining epithelium is rugated and displays a wrinkled eosinophilic cuticle in place of a granular layer.
    • Sebaceous glands characteristically line the cyst wall and open into the cyst.
    • Hair follicles are sometimes present in the cyst wall.
