Henoch-Schönlein purpura (HSP) is an IgA mediated small-vessel vasculitis, more common in children than adults. We present the case of a 37-year-old male who presented with complaints of nausea, vomiting, abdominal pain, purpuric rash over lower extremities, and migratory polyarthralgia five days after being treated with antibiotics for bronchitis. In addition to the abdominal pain, he developed diarrhea and colonic biopsy findings were suggestive of inflammatory bowel disease (IBD). Skin biopsy revealed leukocytoclastic vasculitis with direct immunofluorescence studies (DIF) staining of IgA deposition confirming the diagnosis of HSP. The clinical features of cutaneous eruption with abdominal complaints can be seen with either HSP or IBD; however the specific skin biopsy findings on DIF can distinguish between the two disease processes. Though HSP is primarily seen in the pediatric population, it is a disease process that must be considered in adults presenting with vasculitic skin rashes and abdominal complaints. |
