Ausbreitung eines Zeruminaldrüsenadenoms in das Mittelohr

Abstract

A 37-year-old female presented for surgery with central perforation of the eardrum with granulation. Mastoidectomy had been performed 18 years ago following chronic mastoiditis. As the clinical picture now suggested a suspected cholesteatoma, radiological imaging was performed. The CT scan revealed specification of the mastoid and the tympanic cavity. In addition, MRI scan showed signal enhancement in the same areas. However, the suspected cholesteatoma could not be confirmed intraoperatively. Pathohistology revealed a ceruminal gland adenoma. They are a rare phenomenon and should be distinguished from middle ear adenomas, pleomorph ceruminal gland adenomas, ceruminal gland adenocarcinomas and cylindromas of the ceruminal glands. Owing to a high recurrence rate, complete surgical removal is necessary. Despite its rare occurrence, a ceruminal gland adenoma must be taken into consideration in the differential diagnosis of individual cholesteatoma cases.
