Surgical Treatment by Partial Petrosectomy for a Middle-Ear Carcinoid with Progressive Extension : A Case Report and Review of the Literature

Abstract EN

We herein report a 59-year-old male patient with a recurrent carcinoid tumor of the middle ear 7 years after a tympanomastoidectomy.

The CT and dynamic MRI demonstrated an extensive tumor close to the carotid artery canal and the jugular bulb, and the tumor was removed by a partial petrosectomy with a transmastoid approach.

The histopathological findings revealed a solid and trabecular tumor with cells positive for cytokeratin, chromogranin A, synaptophysin, and CD56.

The MIB-1 antibody for the Ki-67 antigen was positive in 6.6% of the tumor cells.

The relevant literature is reviewed in regard to the present case.
