Rare sellar region tumors.

We present three cases of rare intracranial midline tumor in the sellar region, often mimicking pituitary adenomas clinically. We describe their symptoms, radiological and pathomorphological features. The first case is a pituitary adenoma producing growth hormone with ganglion cell differentiation. In addition, a rare intracranial granular cell tumor of sellar region and germinoma of pituitary fossa are also presented. All tumors were resected and histologically analyzed. Their biological behaviour was favorable with a 10-year follow-up demonstrating no recurrent tumor mass.
