Ectopic pituitary with pregnancy changes in a benign cystic teratoma of the ovary.
We report on the rare finding of pituitary tissue, including both adenohypophysis and neurohypophsis, in a mature cystic teratoma of the ovary removed from a 26 year old female at the time of cesarean section. Immunocytochemistry of the ectopic anterior pituitary component showed pregnancy-related changes that have previously only been described in pituitaries obtained at autopsy.
