A 35-year-old male patient visited our outpatient clinic with sudden onset of right ear fullness. Right tubal stenosis was considered to be responsible for his complaint. A roughsurfaced flat tumor was found close to the right Rosenmuller's fossa, and biopsy was performed immediately under fiberscopy. Whether his hearing loss was due to a conductive or sensorineural disturbance was not conclusively determined because the audiogram was complicated. The tumor was diagnosed histopathologically as not malignant but inflammatory, “epithelioid granulosis in the pharyngeal tonsil”. Physical examinations did not support either sacoidosis or active tuberculosis. The final diagnosis, based on a retrospective study of his lesion, was old epipharyngeal tuberculosis and sudden deafness.
