Pituicytoma is a rare, low-grade neoplasm that originates in the neurohypophysis of the pituitary gland. We report the clinicopathologic features of a pituicytoma arising in a 40-year-old female who presented with menstrual disorder for 2 months, clinically suggestive of a pituitary microadenoma. The tumor was marked by a proliferation of elongated cells arranged in bundles and interlacing fascicles. The tumor demonstrated positive staining with S-100 protein and patchy staining for glial fibrillary acid protein and Epithelial Membrane Antigen. The tumor did not stain with antibodies to Progesterone receptor and Neu-n. An MIB-1 labeling was lower than 1%. The tumor was subtotally resected and didn’t recur after the initial surgery.
