In most of the cases, it is revealed between 40 and 60 year old, by a conductive hearing loss with a greyish mass behind intact tympanic membrane.

The histologics findings show two distinctive type of cells: glandular and neuroendocrine differentiation. The treatment is surgical. A regularly follow up is necessary to diagnostic recurrence.
