Adenomatous Neuroendocrine Tumors of the Middle Ear in a Young Man With Conductive Hearing Loss

ABSTRACT: Neuroendocrine neoplasms of the ear pose a diagnostic challenge because clinical symptoms are no specific. Definite diagnosis is made by histopathological analysis with immunohystochemical evalutation. Therapy consists in a complete surgical resection. Controversial terminology of the neoplasm arises from the differentiation of these tumors composed of both endocrine and exocrine glands. Middle ear localization is an extremely rare presentation but less aggressive than gastrointestinal tract or lung localizations which are the most frequent. Radio-diagnostic analyses are necessary follow-up for preventing or detecting recurrence or metastasis. The authors present a case of neuroendocrine tumor of the middle ear in a young male of 37 years old who presented unilateral right hearing loss and tinnitus. A transcanal tympanoplasty was performed. There were no intraoperative complications and the postoperative period was uneventful.
