This retrospective review of pediatric patients with pituitary tumors causing onset of symptoms by 17 years of age was done to define their pathological distribution, clinical presentation, treatment, and prognosis. Eighteen patients were evaluated and treated from 1979 to 1989. Five had Cushing's disease and 13 had prolactin-secreting tumors. The mean age at the onset of symptoms was 14.7 years, with a range of 7 to 17 years. The mean follow-up period was 4.6 years, and the series consisted of 15 girls and 3 boys. Four of the 5 patients with tumors secreting adrenocorticotropic hormone were girls. The five patients exhibited obesity, hypertension, and growth retardation. The mean age of this group of patients at diagnosis was 12.2 years, and all had intrasellar lesions removed by the transsphenoidal approach. Adenoma was documented in 4 cases by histopathology. There was complete resolution of the endocrinological and clinical abnormalities in each case. The group of patients with prolactinomas comprised 11 girls and 2 boys, and their mean age at diagnosis was 15.7 years. The girls exhibited either primary or secondary amenorrhea. Seven had macroadenomas and 4 had microadenomas. Nine of the 11 girls underwent transsphenoidal resection, and surgery failed in 6, based on hormonal or radiological data. The two boys had suprasellar tumor extension and required multiple surgical procedures plus radiation therapy for control of the tumor mass.
