Primary Adenocarcinoma of the Middle Ear

Abstract

Adenocarcinoma arising from the mucosa of the middle ear is a rare tumor. This report adds four new cases to the 13 cases that have been previously reported in the literature. These neoplasms tend to have a rather slow growth pattern and have an infrequent incidence of distant metastases. The observations that local recurrence is the major problem with adenocarcinoma of the middle ear suggest that aggressive locoregional treatment should be strongly considered.
