Abstract
Spindle cell oncocytoma (SCO) is an exceedingly rare, nonfunctioning, nonadenomatous tumor that arises in the pituitary gland. In 2007, it was classified as a separate pathological entity by the WHO.
SCOs are thought to arise from folliculostellate cells.
In many cases, an SCO may mimic a nonfunctioning pituitary adenoma. As nonadenomatous sellar lesions, however, SCOs also require differentiation from pituicytomas or granular cell tumors.
SCOs typically present with visual loss, hypopituitarism, and headaches.
The mean age at diagnosis is 61 years.
