Abstract
Pituicytoma is a rare benign neoplasm arising in the sellar region, usually found in the posterior lobe and/or pituitary stalk. Here, we report the case of a 67-year-old woman who presented with bitemporal hemianopsia and visual impairment accompanied by mildly elevated prolactin. Pathologic and molecular examination of the tissue removed transsphenoidally revealed 2 distinct tumors: pituitary adenoma and pituicytoma. To the best of our knowledge, histologically proven pituicytoma and pituitary adenoma have never been reported together.
