A Case of Henoch-Schonlein Purpura with Portal Vein and Mesenteric Vein Thrombosis / 대한혈액학회지

ABSTRACT

Henoch-Schonlein purpura is an immunologically mediated systemic leukocytoclastic vasculitis of small vessels that is characterized by symmetric nontraumatic, nonthrombocytopenic, painless palpable purpura on the lower extremities and buttock, arthralgias on usually the knees and ankles, gastrointestinal symptoms and glomerulonephritis. Although the jejunum and ileum are most frequently affected, any portion of gastrointestinal tracts may be involved. Generally, gastrointestinal manifestations of Henoch-Schonlein purpura are the edematous wall of involved bowel, submucosal hemorrhage and erosion. We experienced a 56-year-old man with Henoch-Schonlein purpura who initially presented acute abdominal pain with portal vein and superior mesenteric vein thrombosis.
