null-cell adenoma

 

Definition: an adenoma of the hypophysis composed of cells for which there is no overt evidence of hormone production, but which usually produces hypopituitarism and visual disturbances by compression of adjacent structures; approximately one third of these tumors have cells with abundant mitochondria (oncocytes) that are somewhat larger than the monocytic null cells.

Synonym(s): undifferentiated cell adenoma
