Pyoderma Gangrenosum (PG) is a distinctive dermatologic condition characterized by recurrent inflammatory ulcers, often manifesting with violaceous borders and undermined edges. We describe a 40-year-old male who presented with acute on chronic necrotic ulcer of the left index finger following foreign body penetration. Despite multiple emergency department visits and treatments for presumed recurrent cellulitis, including various debridements, his condition persisted without symptomatic relief. A high index of clinical suspicion, due to recurrent presentations and potential pathergy, prompted an excision biopsy which confirmed Pyoderma Gangrenosum (PG). Regrettably, due to delays in appropriate management, the patient chose amputation because of intolerable pain, highlighting the critical importance of timely diagnosis for optimal patient outcomes.
