Superficial Granulomatous Pyoderma Successfully Treated with Intravenous Immunoglobulin.

Superficial granulomatous pyoderma is a relatively rare variant of pyoderma gangrenosum, characterized by superficial ulceration with a vegetative margin and a clean granulating base. Ulcers in superficial granulomatous pyoderma are typically located on the trunk and may follow minor trauma. It may be misdiagnosed as classic pyoderma gangrenosum, despite having distinct characteristics. Here we report a case of superficial granulomatous pyoderma successfully treated with intravenous immunoglobulin (IVIg).


LEARNING POINTS
Superficial granulomatous pyoderma is a rare variant of pyoderma gangrenosum.Histopathological and clinical characteristics of superficial granulomatous pyoderma are distinct from those of classic pyoderma gangrenosum.Superficial granulomatous pyoderma is often slow-growing and is only rarely linked to underlying systemic disease.IVIg may be an effective treatment option for superficial granulomatous pyoderma.
