The patient was a 32 year-old man who was first seen in 2003 for 2 years hearing loss. On otoscopic examination, a whitish mass could be observed through the intact tympanic membrane. High resolution computed tomography showed a tumor like lesion in the middle ear with no evidence of bone destruction. A tympanomastoidectomy was performed. Light microscopy showed fragments of cellular tissue in which both glandular and trabecular growth pattern could be identified Immunohistochemical examinations showed positive staining of the tumor cells for cytokeratin and chromogranin. The diagnosis of carcinoid tumor should be considered in all cases of adenomatous neoplasms of the middle ear and mastoid. Conservative surgical excision is the treatment of choice, and local recurrence following complete excision is uncommon.
