[Fatal hyperparathyroidism]

Hyperparathyroidism is able to determine suddenly after a very poor clinical history a deep coma : in such a condition, the diagnosis with the paraneoplastic hypercalcemia may be a difficult one : cervicotomy can be the heroïc way to lead to diagnosis and in the same time to perform treatment. To avoid such a dramatic situation, the authors propose cervicotomy for every patient suspected of P.T.H. adenoma, when calcemia is higher than 115 mg c/l, even if the symptoms are very slight or nil.
