Syndrome of galactorrhea, amenorrhea, and obesity as possible indicators of prolactinoma: a case study approach.

Four female patients were found to have microadenomas and high prolactin levels, but the symptoms of the syndrome varied among the patients. Three of four patients had overt galactorrhea, obesity, and amenorrhea. One patient was postmenopausal, and another showed menstrual irregularities. Two patients sought medical attention for headaches, and one for visual disturbances. Two patients previously had used psychotropic drugs, and two patients used birth control pills. When tested, all patients had high serum prolactin levels, abnormal sellar tomograms, and the presence of microadenoma of the pituitary was confirmed by computerized tomography.Because of the high incidence of pituitary tumor among these four patients, this study suggests that a complete workup should be done for patients having galactorrhea, amenorrhea, and obesity as a syndrome or as separate entities.
