Cutaneous Vasculitis, Interstitial Pneumonia with Crazy-Paving Appearance, and Positive pANCA in a Patient with Severe Crohn’s Disease

Abstract EN

Cutaneous vasculitis, interstitial pneumonia with crazy-paving appearance on high-resolution computed tomography, and repeated positive perinuclear anti-neutrophil cytoplasmic antibodies (pANCA) are rarely found together in patients with inflammatory bowel disease in the existing literature.

We report the case of a Chinese patient previously diagnosed with cutaneous vasculitis and interstitial pneumonia, who presented with acute pain and mass in his right lower quadrant a couple of years later.

The terminal ileum biopsy and postoperative pathology confirmed Crohn’s disease (CD).
