title: [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.
