METHODS: We present the case of a 78-year-old man in the emergency department with findings of weakness, abdominal pain, and bloody diarrhea for 3 days and a new-onset bilateral lower extremity rash. Diagnostic imaging and labs diagnosed this patient with immunoglobulin A vasculitis (IgAV) with associated acute kidney injury and abdominal mesenteric edema. Why Should an Emergency Physician be Aware of This? Recognition of IgAV by emergency physicians and assessment of multiple organ involvement is critical to expedite treatment and minimize complications. Particularly, physicians should consider and recognize the increased severity and different presentation of IgAV in adults in comparison with the more widely known manifestation in children.
