title: The sphenoid sinus: an unusual presentation of a typical carcinoid tumor.
abstract: Carcinoid tumors are neuroendocrine tumors that are most commonly found in the gastrointestinal tracts and lungs. They seldom develop in the head and neck area as a primary tumor, and there have been rare reports of them arising in the sinonasal area. We report a case of a 47-year-old woman with a typical carcinoid tumor arising in the sphenoid sinus.
