[A rare association of postpartum thyroiditis and ulcerative colitis].

It is well known that chronic thyroiditis is frequently associated with other autoimmune disorders, but its association with inflammatory bowel diseases has rarely been described. We report a case of a 26-year-old woman, seven months after delivery, who developed a moderate attack of ulcerative colitis. Laboratory analysis, ultrasonography, anti-thyroid antibodies and cytological examination of fine needle aspiration biopsy led us to diagnose postpartum thyroiditis. The patient also presented erythema nodosum, anti-parietal cell and anti-intrinsic factor antibodies and a family history of autoimmune disorders. This case illustrates the need for clinical awareness of concomitant postpartum thyroiditis and ulcerative colitis and suggests that in patients with inflammatory bowel diseases thyroid function test should be carried
