Immunoglobulin A (IgA) vasculitis is an IgA-mediated disease that mainly affects small blood vessels and occurs less frequently in adults [6]. IgA vasculitis presents with purpura, arthralgias, inflammatory bowel disease, and renal dysfunction [6,7]. Literature analysis revealed a case of IgA vasculitis as an adverse reaction to PTU overdose [8]. However, there remains an unclear understanding of the relationship between PTU and IgA vasculitis [9]. Here, CD79A is linked to Henoch-Schoenlein purpura.
