Pituitary chromophobe adenoma in a cat

Abstract

Chromophobe adenoma was diagnosed in the pituitary gland of an 11 yr old domestic shorthaired cat. Histologically, the tumor consisted of a mass of cells with scant sinusoidal arrangement and connective tissue stroma and few blood vessels. In areas the neoplastic cells contained large vacuoles that occupied the entire cytoplasm and pushed the nuclei aside.
