title: Atypical pyoderma gangrenosum mimicking an infectious process.
abstract: We present a patient with atypical pyoderma gangrenosum (APG), which involved the patient's arm and hand. Hemorrhagic bullae and progressive ulcerations were initially thought to be secondary to an infectious process, but a biopsy revealed PG. Awareness of APG by infectious disease services may prevent unnecessary use of broad-spectrum antibiotics.
