These cysts usually arise on hair-bearing areas including the scalp, face, neck, trunk, extremities, and scrotum [2 – 7]. Infrequently these lesions cause symptomatic spinal cord compression [2]. The clinical presentation of a cyst depends on it volume, site and its relationship to the surrounding bony and neural structures. Subcutaneous epidermal cysts commonly involve the scalp, face, neck, trunk, and back; fewer than 10% occur in the extremi- ties [2]. They result from inclusion of ectodermal elements during neural tube closure, and typically present in middle age due to mass effe On US, subcutaneous epidermal inclusion cysts are usually well-circumscribed, oval-shaped, mildly echogenic masses with occasional linear anechoic and/or echogenic reflections, increased through-transmission, hypoechoic rim and no Doppler flow. Surgical excision was performed, and the histopathological diagnosis was an epidermal inclusion cyst.
