Acromegaly: A Review of 100 Cases

Clinical and pathological findings in 100 cases of acromegaly were reviewed. Great individual variation in manifestations of the disease was apparent. The chronic course was evidenced by 30 patients presenting symptoms unrelated to acromegaly. Headache, visual disturbances, arthritis and elevated blood pressure were common. The incidence of diabetes mellitus, thyroid and adrenal dysfunction was similar to that reported in other series. Gonadal disturbances were frequent. Two patients had galactorrhea and two had hyperparathyroidism. Radiologically, pituitary fossae were normal in 24. Pituitary histology in 29 cases revealed four eosinophilic adenomas, but most were mixed eosinophilic-chromophobic. Fifty-two patients received radiation therapy. Rhinorrhea and optic nerve fibrosis were seen in this group. Twenty-four patients were operated upon, with no operative deaths since 1945 and no morbidity since 1952. Visual failure was the clearest indication for surgery. Treatment will be difficult to evaluate until an index of growth hormone secretion is generally available.
