Germinoma of the pituitary gland; a report of two cases.

Intracranial germinomas are usually situated in the pineal, but sometimes they arise in the infundibular region of the third ventricle (ectopic pinealoma) and may rarely extend down into the pituitary fossa. Two cases of germinoma arising within the pituitary gland and presenting with hypopituitarism, are described; no report of any similar cases could be found.
