title: A case of syryngocystadenoma papilliferum (SCAP) involving middle ear, presenting with otomastoiditis and cerebral abscess.
abstract: Syryngocystadenoma papilliferum (SCAP) is an uncommon cutaneous adnexal neoplasm of apocrine gland origin. Until now, fewer than 200 cases have been reported in international literature, of which 12 cases involved the external ear. No cases of SCAP involving the middle ear have been reported. We describe a case of SCAP of external and middle ear, presenting with otomastoiditis and cerebral abscess; this aggressive behavior, never reported for a benign adenoma of the external or middle ear, could lead to a differential diagnosis with cholesteatoma or malignancies.
