Intussusception associated with Henoch-Schonlein purpura.

Henoch-Schonlein purpura is a clinical diagnosis, based on a presentation including rash, arthralgia/arthritis, and abdominal pain, often with renal complications. A rare complication is intussusception, presumably initiated by an edematous vasculitic leading point in the small bowel's mucosal surface. A case is described involving a 3-year-old male, with a brief review of the literature.
