title: Ulcerative colitis masked by giant urticaria.
abstract: The occurrence of giant urticaria and ulcerative colitis is very infrequent. A 23 year-old female reported the initial eruption of short-lived cutaneous itchy weals on her arms. Then lesions ran together and became confluent, extending to her legs, followed by undefined abdominal pain and a slight increase of body temperature. Exams showed hystologically confirmed ulcerative colitis, with perinuclear anti-neutrophil cytoplasmic antibody positivity. Ulcerative colitis therapy led not only to the remission of the colitic symptoms, but also to the prompt recovery of skin manifestations. Urticaria was the epiphenomenon of ulcerative colitis.
