Abstract and Introduction
Introduction: Superficial granulomatous pyoderma (SGP) is a rare variant of pyoderma gangrenosum (PG) and differs from classic PG in its indolent clinical course, lack of associated underlying disease, the finding of a granulomatous infiltrate on histology, and better prognosis with less-aggressive therapies.
Methods: We report on a case of SGP involving the face following local reexcision of a biopsy scar.
Results: The patient developed an indolent ulceration following an excision of an unfavorable scar on her face.
Discussion: Superficial granulomatous pyoderma is usually responsive to conservative treatment with antibacterial or local anti-inflammatory agents. Facial involvement with SGP is particularly rare and tends to be more refractory to conservative management. Superficial granulomatous pyoderma involving the face appears to respond better to intensive treatment with systemic corticosteroids or immunosuppressants. To prevent poor cosmetic and functional outcomes in patients with nonhealing lesions, it is important for surgeons to recognize the clinical and histopathologic presentation of SGP and consider initiating a more aggressive management approach for SGP involving the face.
Superficial granulomatous pyoderma (SGP) is a rare, slowly progressive, and superficial variant of pyoderma gangrenosum (PG) that was first described by Wilson-Jones and Winkelmann in 1988. Both classic PG and SGP are progressive ulcerative diseases of the skin that may demonstrate pathergy, the phenomenon whereby ulcerative lesions can be induced at sites of skin trauma. Superficial granulomatous pyoderma differs from PG in its indolent clinical course, lack of associated underlying disease, the finding of a granulomatous infiltrate on histology, and better prognosis with less-aggressive therapies.[1,2] To date, there are approximately 60 cases of SGP that have been described worldwide, with facial involvement present in only 6 of these cases.[1–9] In this report, we describe a case of SGP involving the face and present a review of the literature.
