title: [Clinical symptoms of hyperparathyroidism and sizes of the parathyroid gland tumors].
abstract: Three groups of patients with different degrees of primary hyperparathyroidism were compared: 36 patients with asymptomatic tumors (incidentalomas) of the parathyroid glands, 20 patients with parathyreoadenomas of medium size and mild signs of hyperparathyroidism and 26 patients with large adenomas and severe manifestations of the disease. It was shown that asymptomatic tumors of the parathyroid glands (incidentalomas) might turn into clinically marked hyperparathyroidism as the size of the parathyroid tumors was growing.
