REPORT OF 2 CASES

CASE 1

A 63-year-old man with a history of diabetes, hypertension, depression, and stroke presented with a 1-week history of diarrhea, nausea, arthralgia, and acral purpuric eruption as well as progressively increasing abdominal pain. On examination he was noted to have palpable purpura on his hands and feet (Figure 1), bloody stool, and abdominal distention. Petechial hemorrhages throughout the small bowel were discovered on exploratory laparotomy. Laboratory findings revealed hematuria, elevated serum urea nitrogen and creatinine levels, and an increased sedimentation rate. Skin biopsy results showed a leukocytoclastic vasculitis and granular deposition of IgA (Figure 2), IgM, and C3 in capillaries consistent with Henoch-Schönlein purpura (HSP). Test results for antinuclear antibodies, antineutrophil cytoplasmic antibodies, viral hepatitis, cryoglobulins, and cryofibrinogens were all negative.
