Rectal perforation in a 42-year-old woman due to Henoch-Schönlein purpura: a case report.

Henoch-Schönlein purpura (HSP) is caused by deposition of IgA-containing immune complexes within the blood vessels. HSP mostly occurs in children and is less common in adults. In addition to palpable purpura, arthritis or arthralgia, renal disease and abdominal pain, gastrointestinal symptoms occur in 50% of children. These can be caused by gastrointestinal hemorrhage, bowel ischemia and necrosis, intussusception, and bowel perforation. In adults, intussusception is less frequent than in children. We report a 42-year-old woman referred to our hospital with acute abdominal pain. After laboratory and radiologic examinations, laparatomy was performed which revealed rectal perforation due to HSP. HSP is a multisystem disorder. Abdominal pain in patients with HSP may herald a serious gastrointestinal problem also in adult patients.
