Dermoid cyst

    Clinical Features:

    • Usually congenital, rubbery cyst, often with fine hairs on its surface
    • Most commonly periocular

    Histologic Features:

    • Dermal or subcutaneous cyst lined by squamous epithelium with a granular layer
    • The cyst contains keratin and sometimes hair shafts.
    • Hair follicles empty into the cyst wall, which is often also associated with sebaceous and sweat glands.
    • Distinguished from epidermal cysts by the adnexal structures associated with the cyst wall
    • Distinguished from steatocystoma by the thicker lining without a cuticle and by the greater number and type of adnexal structures associated with the cyst wall
