A Case of Henoch-Schonlein Purpura with Duodenal Involvement / 대한소화기내시경학회지

ABSTRACT

Henoch-Schonlein purpura is a form of systemic small-vessel vasculitis characterized by vascular purpura, predominantly occured on the lower limbs and articules with gastrointestinal and renal symptoms. The symptoms occur consecutively and purpura is the most common initial manifestation but if another symptoms prevails, the diagnosis often can be delayed. Any portion of the gastrointestinal tract distal to the esophagus may be involved, but most frequently affected sites are jejunum and ileum. Mucosal lesions found predominantly in the second portion of the duodenum seem to be characteristic of Henoch-Schonlein purpura and may assist the diagnosis in patients with atypical nonspecific symptoms. We report a case of Henoch-Schonlein purpura with the characteristic endoscopic finding in the second portion of duodenum, which helps to make the correct diagnosis and proper management of the patient.
