title: Benign adenomatous neoplasm (adenoma) of the middle ear.
abstract: This presentation is a study of the pathogenesis, clinical behaviour and therapeutic response of 20 cases of a primary adenomatous neoplasm confined to the middle ear cleft. The investigation supported origin of the tumour from the middle ear mucosal epithelium. Clinical behaviour was that of a benign, localized, non-metastasizing neoplasm. Simple localized surgical removal of the tumour afforded an excellent prognosis in all cases. The designation of the tumour entity as adenoma of middle ear is proposed.
