Infliximab treatment for large, multifocal, abdominal pyoderma gangrenosum associated with ulcerative colitis: A case report.

Pyoderma gangrenosum is an uncommon neutrophilic dermatosis that is highly associated with pathergy in the setting of trauma or surgery, systemic disease, or may be idiopathic. Herein, we present the case of a 68-year-old female with ulcerative colitis who underwent a subtotal colectomy with an end-ileostomy and presented post-operatively with large, multifocal pyoderma gangrenosum at two abdominal sites. She was managed with intralesional triamcinolone injections and high-dose systemic steroids and was transitioned to IV infliximab. Our case report illustrates the role of infliximab in the treatment of complicated multifocal pyoderma gangrenosum and contemplates the impact of systemic infliximab exposure.
