Occurrence of other endocrine tumours in primary hyperparathyroidism

In a review of a hundred and nineteen patients with primary hyperparathyroidism an unexpectedly high number (17.5%) were found to have evidence of associated endocrine disease and were deemed to have multiple endocrine adenomatosis (M.E.A.). The clinical pattern of hypercalcaemia in no way distinguished these patients from other hyperparathyroid patients. M.E.A. was most commonly found in patients with several diseased parathyroid glands.
