Choristoma of the middle ear is a rare condition characterized by the presence of normal salivary gland tissue in the middle ear space. Salivary gland choristomas are benign lesions that are frequently associated with ossicular chain and facial nerve anomalies. Total surgical excision is indicated when there is no risk of damaging the facial nerve. We describe a new case of salivary gland choristoma of the middle ear, and we discuss the etiology, histologic features, and management of such lesions. Our patient was a 22-year-old woman in whom we surgically removed a whitish retrotympanic mass. Intraoperatively, we also detected an ossicular chain malformation. Histologic examination of the choristoma revealed the presence of salivary gland tissue. Furthermore, the lesion contained an extensive and previously undescribed component: a well-defined pseudostratified respiratory-type epithelium, similar to that of a normal eustachian tube. Ten months after removal of the choristoma, we surgically repaired the ossicular chain anomalies. No recurrence was noted on follow-up.
