[Rare association of hypoparathyroidism and mediastinal-pulmonary sarcoidosis]. / Association rare d'une hypoparathyroïdie et d'une sarcoïdose médiastino-pulmonaire.

We report the case of a 52-year-old woman who presented hypoparathyroidism and sarcoidosis. The hypoparathyroidism developed 8 years after the diagnosis of sarcoidosis. No element in favor of an autoimmune disease of the parathyroid could be evidenced. Pathology and immunology blood tests were equally noncontributive. Another pathophysiological mechanism, possibly sarcoidic granulomatous infiltration of the parathyroid glands, was suspected. The patient also presented apparently coincidental vitiligo.
