[Scleroderma with anomalies of the thyroid function. 7 cases]

Thyroid function, studied in 36 scleroderma patients revealed 7 abnormal cases: 6 hypothyroid patients secondary to autoimmune thyroiditis and 1 hyperthyroidism secondary to Graves' disease. In the hypothyroid subgroup, 3 cases presented a localized systemic sclerosis and the 3 others presented a diffuse systemic sclerosis; Sjögren syndrome was found in 2 of these patients. The hyperthyroid patient presented a diffuse systemic sclerosis. Because of the association between scleroderma and thyroid diseases, we suggest to perform thyroid screening regularly for all patients with systemic sclerosis.
