title: [A case report of anaphylactoid purpura with acute abdominal pain secondary to trauma caused by traffic accident].
abstract: A 17-year-old man was admitted to our hospital with multiple fractures resulting from traffic accident. After treatment of fractures, his general status was improved. However, one month after traffic accident, he suffered severe pain in the epigastrium. Ultrasonography and computed tomography showed thickening of the intestinal wall in the duodenum, ileum, and ascending colon. Nineteen days after the onset of abdominal pain, small hemorrhagic spots appeared on both of the lower legs. Subsequently, he developed proteinuria and hematuria. Purpura nephritis was diagnosed in biopsy specimens of the kidney. Anaphylactoid purpura associated with traffic accident is very rare and it is difficult to diagnose without skin and renal symptoms.
