Pyoderma Gangrenosum in an African American Male Initially Presenting as Sepsis.

Pyoderma gangrenosum (PG) is a rare, ulcerating, rapidly developing neutrophilic dermatosis that is often challenging to diagnose and treat. We present the case of a 47-year-old African American male who presented with a painful left anterior shin ulcer, fever, leukocytosis, and tachycardia. The patient had a similar lesion seven years prior that had since healed, with no other medical conditions. Sepsis secondary to a soft tissue infection was initially suspected; however, given the patient's history of pathergy, rapid progression of the lesion, skin examination, and sterile wound culture, PG was diagnosed. The patient improved in response to corticosteroid therapy. A brief overview of the disease presentation, diagnosis, and treatment is provided.
