Anterior pituitary component in benign cystic ovarian teratomas. Report of three cases.

This paper documents three cases of benign cystic ovarian teratoma in which elements of adenohypophysis was recognized as one of the tissue components. Such findings have been recorded but not unequivocally documented in any of the previous reports of benign cystic teratomas. One of the tumors in this series also contained neuroglial tissue closely associated with the adenohypophyseal elements. The possibility that these neural elements might represent neurohypophysis is briefly discussed.
