Abstract:
Adenomatous tumors are an uncommon cause of a middle ear mass. Clinical findings may be nonspecific, leading to difficulties in differentiation from other middle ear tumors. Controversy also exists whether to classify middle ear adenoma and carcinoid as separate neoplasms, or alternatively within a spectrum of the same pathologic entity. Most adenomatous middle ear tumors are indolent in behavior, with a benign histologic appearance and slowly progressive growth. The mainstay of treatment is complete surgical resection, which affords the greatest likelihood of cure.
