An Unusual Faint Halo Around Colonic Ulcers

Question: A 47-year-old woman presented with a 1-month history of abdominal pain, fever for 10 days, and tarry stool. She reported recurrent mouth and genital ulcers since childhood. The patient had no family history of mouth and genital ulcers, and never consulted a doctor. On examination, she had tenderness in the right iliac fossa with no mass. Blood examinations revealed elevated C-reactive protein of 225 mg/L (normal range, 0–12 mg/L) and decreased hemoglobin of 111 g/L (normal range, 130–175 g/L).
