Pituitary tumors associated with hyperprolactinemia and polycystic ovarian disease

Galactorrhea and hyperprolactinemia, or both, have been described in some patients with polycystic ovarian disease. Three patients who had had previous bilateral wedge resection of the ovaries and who manifested persistent amenorrhea were found to have elevated levels of serum prolactin (180 to 540 ng/ml) 5 to 10 years later. All three patients initially demonstrated moderate hirsutism and failed to experience withdrawal bleeding after administration of progesterone or clomiphene citrate. Polytomographic evidence suggestive of an intrasellar tumor was present when elevated serum prolactin levels were noted. (Routine sellar roentgenograms prior to wedge resection had been reported as normal.) Two of the three patients underwent transsphenoidal surgery with removal of an 8-mm diameter chromophobe adenoma in each instance. Although serum prolactin levels decreased to 32 and 102 ng/ml, respectively, amenorrhea has persisted with gradual cessation of galactorrhea over a 1- to 2-year follow-up period. Our experience with the reported three cases supports the conclusion that in some cases an association may exist between polycystic ovarian disease and prolactin-producing adenomas.
