Middle Ear Carcinoid Tumor with External Auditory Canal Extension: A Case Report.

The middle ear cavity is an uncommon location for neuroendocrine tumors. They commonly appear as retrotympanic masses, with intact tympanic membrane, and rarely mimic acquired cholesteatoma, as in our case. The clinical and radiological findings are not specific; therefore, the final diagnosis is often delayed. We present a rare case of a middle ear carcinoid tumor with external auditory canal extension that was treated successfully with radical mastoidectomy with no evidence of recurrence or metastasis at 16 months of follow-up.
