title: Concomitant primary hyperparathyroidism, Graves' disease and vitamin D deficiency.
abstract: The simultaneous occurrence of hyperthyroidism and primary hyperparathyroidism is quite rare. A case is reported here of Graves' disease and primary hyperparathyroidism. Treatment of these concomitant diseases consists in combined thyroidectomy and parathyroidectomy. Histological examination confirmed Graves' disease and revealed the presence of a parathyroid adenoma in one gland and parathyroid hyperplasia in another one. After surgical treatment, secondary hyperparathyroidism due to 25-OH Vitamin D deficiency appeared. To our knowledge, this is the first case in which a Vitamin D absorption deficit was found in presence of hyperthyroidism and hyperparathyroidism without other intestinal absorption deficits. Diagnostic and follow-up difficulties related to these three concomitant pathological conditions are discussed.
