Abstract
Pyoderma gangrenosum is an uncommon neutrophilic dermatosis characterized by an ulcerative lesion with a violaceous border. Most frequently, these lesions present in the lower extremity and are associated with underlying immune-mediated comorbidities. Infrequently, these lesions may present in the upper extremity, which presents difficult challenges for upper extremity surgeons as the lesions are frequently misdiagnosed as an infectious process. This often leads to inappropriate surgical debridement and antibiotic administration. Local trauma to the lesion can lead to a process of pathergy and worsening of the lesion. Here, we report on a case of cutaneous pyoderma gangrenosum affecting the dorsal hand, originally misidentified as an atypical infection with subsequent unsuccessful surgical debridement. After involvement of a multidisciplinary team, appropriate diagnosis was made, and treatment with local immunosuppressive agents achieved resolution of the lesion.
