title: Pituitary-containing benign cystic teratoma arising from the uterosacral ligament.
abstract: We report on the incidental finding of pituitary tissue in a mature teratoma on the uterosacral ligament of a 56-year-old woman who underwent exploratory laparotomy for ovarian masses. While the occurrence of pituitary tissue has been reported rarely in benign cystic teratoma of the ovary, and while pituitary adenomas can occur in ectopic sites, we have found only one report in the literature of benign cystic teratoma of extragonadal origin composed of mature adenohypophyseal and neurohypophyseal elements.
