[Sarcoidosis and hyperthyroidism (author's transl)].

The authors report the case of a 31-year-old man with thyrotoxicosis which occurred four months after the discontinuation of long-term corticosteroid therapy for sarcoidosis. Clinical and biological features of thyrotoxicosis were reversible when corticosteroid therapy was reinstated. A review of 27 cases from the literature provides the opportunity to recall the characteristic features of hyperthyroidism associated with sarcoidosis: female prevalence, usual presence of sarcoidosis at onset, secondary occurrence of hyperthyroidism, necessity for simultaneous treatment of both diseases, since corticosteroid therapy alone is infrequently sufficient.
