Glomus tumors of the sellar region are exceedingly rare with only two reported cases in the literature. A case of a sellar glomangioma in a 72-year-old man is described. The tumor had the radiographic and gross appearance of a pituitary adenoma. Microscopically, the tumor was composed of epithelioid cells surrounding prominent small vascular channels. The tumor cells had indistinct cell borders and monotonous nuclei. Histological and immunohistochemical analysis identified the sellar tumor as a glomangioma. Here, we report the clinicopathological features of a third case of a sellar glomus tumor and review the literature.
