Middle Ear Adenoma with Uncommon Presentation: A Case Report

Adenomas of the middle ear are even rarer. Although considered benign tumors, they carry a risk of recurrence and malignant transformation. We present a 37-year-old patient with a hypoacusis of the left ear with purulent otorrhea on a non-marginal tympanic perforation as symptomatology. The audiogram showed transmission deafness, and the scanner found a fleshy attic mass with a preserved ossicular chain. The patient underwent an antro-atticotomy with mass excision, the anatomopathological result of which was in favor of an adenoma of the middle ear. The patient has shown no recurrence for almost 2 years. In conclusion, middle ear adenomas are rare neoplasms and have no specific symptoms or clinical presentation. Total exploration and extirpation is required for treatment, and microscopic and immunohistochemical examinations are mandatory for a definitive diagnosis.
