[Sarcoidosis associated with hypothyroidism due to thyrotropin-receptor blocking antibodies]. / Syndrome de Löfgren associé à une hypothyroïdie par anticorps bloquant les récepteurs de la TSH.

The association of sarcoidosis and auto-immune thyroid disease has been reported. We report a 29-year-old woman, treated for hypothyroidism caused by thyrotropin-receptor blocking antibodies, who developed a sarcoidosis (Löfgren's syndrome). Auto-immune thyroid diseases and sarcoidosis could share common pathogenic mechanisms.
