[A case of sarcoidosis with simultaneous primary hyperparathyroidism, coincedence or consequnce?]

Abstract

We have reported of a case of generalised sarcoidosis with primary hyperparathyroidism. A pathogenetic relation between sarcoidosis associated with hypercalcemia and the development of parathyroid adenoma will be discussed and a causal connection will be proposed. According to our hypothesis every primary hyperparathyroidism could have developed from regulatory hyperfunction. This is illustrated by sarcoidosis with hypercalcemia and hypercalcuria. In this case a disturbance in vitamin D dependent calcium metabolism induces hyperplasia of the parathyroid which later leads to the development of a parathyroid adenoma. In addition a review of literature describing similar cases is given.
