Granular cell tumor of the pituitary fossa.
Although granular cell tumors are relatively common in the head and neck, symptomatic granular cell tumors of the neurohypophysis are extremely rare. Ophthalmologic symptoms are most common, followed by endocrinologic manifestations. We report a case of a granular cell tumor of the pituitary fossa that was surgically treated. The clinical manifestations, radiographic appearance, and surgical management of granular cell tumors of the pituitary fossa are reviewed, as well as the unique histopathology and electron microscopy of this uncommon neoplasm.
