[Postpartum thyroiditis and Basedow disease].
BACKGROUND
The postpartum period is characterized by a rebound in autoimmunity secondary to immune tolerance induced by pregnancy, creating favorable conditions for flare up of Graves' disease or autoimmune thyroiditis. Postpartum thyroiditis is a recognized clinical entity.


METHODS
Six years after onset of Graves' disease treated with antithyroid drugs, a 25-year-old woman had a high serum level of antithyroperoxidase antibodies a few months before she became pregnant. Six weeks after delivery, she developed signs of hyperthyroidism and goiter. The diagnosis of postpartum thyroiditis was retained. Her condition regressed spontaneously to euthyroidism then hypothyroidism.


CONCLUSIONS
The therapeutic options involved underline the importance of distinguishing between Graves' disease and postpartum thyroiditis. The diagnosis of postpartum thyroiditis is based on history taking, clinical findings, and laboratory tests, especially isotope uptake.
