Necrotic Ulceration of the Hand Case Review: Think Beyond Infection.

Neutrophilic dermatosis of the dorsal hands is a rare neutrophilic dermatosis that can be associated with inflammatory bowel disease, rheumatoid arthritis, and underlying malignancies. The occurrence of trauma as an initiating factor and its early features of pain and inflammation followed by blistering or ulceration mean that it can be mistaken for necrotizing infection. Neutrophilic dermatosis of the dorsal hands should be considered in all patients who present with such features confined to the back of the hands, particularly those with negative microbiological results or lack of response to antibiotic therapy. A case review design was used to analyze the presentation of a woman aged 65 years in the United Kingdom, seeking care for a painful rash on the hand in the emergency department that was subsequently diagnosed as neutrophilic dermatosis of the dorsal hands. Emergency clinician awareness of neutrophilic dermatosis of the dorsal hands as a rare differential diagnosis for patients presenting with necrotic ulceration may prevent unnecessary antibiotic therapy and surgical intervention.
