Bowel-associated dermatosis-arthritis syndrome: bowel bypass syndrome without bowel bypass.

The bowel bypass syndrome is a well-recognized complication in patients who have had jejunoileal bypass for morbid obesity. It consists of an influenza-like illness with increased temperature, chills, polyarthralgia, myalgia, and inflammatory papules and pustules that are 2 to 4 mm in diameter and that usually appear on the extremities and the upper part of the trunk. A patient is reported who had an identical bowel-associated dermatosis-arthritis syndrome but who had not undergone a jejunoileal bypass operation. Seven previously reported similar cases are reviewed.
