Middle Ear Salivary Gland Choristoma: A Case Report.

Salivary gland choristoma of the middle ear cavity is a very rare condition. These lesions are a result of a defective embryonic development and their adjacent structures may be associated with abnormalities. Here we report a case of salivary gland choristoma of the middle ear who presented to Be'sat Hospital, Tehran, Iran in 2015 with unilateral conductive hearing loss. There are 41 case reports in English and non-English literature from 1961. Taylor and Martin reported the first case of middle ear salivary choristoma.
