title: Crush cytology of pituicytoma.
abstract: The crush cytology of a pituicytoma is reported. The lesion was resected from a 54-yr-old man with a 7-mo history of headache. The intraoperative crush smears revealed plump spindle cells with elongated, nonwavy nuclei, and moderate, finely granular cytoplasm with distinct cytoplasmic borders. These cells were arranged in cohesive fascicles exhibiting a storiform pattern focally. Cytologically, this lesion can be differentiated from pituitary adenoma, astrocytoma, meningioma, and schwannoma.
