Superficial granulomatous pyoderma (SGP) is a rare pyoderma gangrenosum (PG) variant that differs from classic PG in that the ulcers tend to be more superficial, lack a rapidly advancing border, and are not typically associated with an underlying systemic disease. The ulcers are most commonly painless and located on the trunk, with a clean granulating base. They generally do not show undermining but may have a vegetative border. Lesions usually respond well to either topical or intralesional corticosteroids with complete healing. The classic histopathologic finding is a "three-layer granuloma" in the superficial dermis consisting of central neutrophilic inflammation and necrosis, a surrounding layer of histiocytes and multinucleated giant cells, and an outer most layer of plasma cells and eosinophils. Herein, we present a unique case of SGP with sporotrichoid-like distribution on the lower extremity. |
