Salivary gland choristoma defined as the architecturally normal salivary gland tissues found in abnormal locations. This condition can be diagnosed based on histopathological investigations. Because middle ear salivary gland choristoma usually present with middle ear mass and conductive hearing loss, other tumorous conditions of the middle ear, including glomus tumor or facial nerve schwannoma should be ruled out. We present a case of middle ear mass in a in a 6-year-old boy. A pinkish mass was incidentally found behind the normal tympanic membrane. Pure tone audiometry showed the conductive type of hearing loss with the threshold of 50dB. Magnetic resonance image revealed the enhancing mass in middle ear suggesting glomus tumor. Although selective embolization could not perform owing to fail to identify the feeding vessel, we planned the surgical exploration. A pulsatile lobulated mass that adhered to the facial nerve was identified. However, the mass was easily dissected without profuse bleeding. Histopathology finally confirmed the salivary gland choristoma. We discuss the clinical features and management of middle ear salivary choristoma with a review of literatures.
