Spindle cell oncocytomas and granular cell tumors of the pituitary are variants of pituicytoma.

The American journal of surgical pathology - 1 Nov 2013

Mete Ozgur, Lopes Maria Beatriz, Asa Sylvia L

Abstract excerpt

Pituicytomas are neoplasms that arise from pituicytes, which are specialized glia of the posterior pituitary. Pituicytes have 5 ultrastructural variants: light, dark, granular, ependymal, and oncocytic. Granular cell tumors of the pituitary gland are thought to arise from granular pituicytes. Spindle cell oncocytomas are considered to arise from folliculostellate cells, which are sustentacular cells of the...
