title: Pyoderma gangrenosum: a difficult diagnosis best managed in a burn treatment center.
abstract: Pyoderma gangrenosum (PG) is a rare immunological disorder with inexplicable white blood cell infiltration into the epidermis with necrosis and excruciating pain. Diagnosis is by exclusion which delays proper treatment. Surgical intervention often exacerbates wounds. Between 2004 and 2010, seven patients with PG were admitted to our burn treatment center (BTC). Multiple treatment modalities were used on these patients. An institutional review board-approved retrospective study investigated seven PG BTC admissions. Demographic information, symptom onset, time to diagnosis, admission or transfer, length of stay (LOS), use of corticosteroids, and prior surgery were collected. The average time to PG diagnosis was 18.7 days and the average wound surface area was 3.9%. The average patient age was 64.6 years (median 66 years) and there were five men and two women patients. The average symptom onset was 70.5 days prior to BTC admission. The BTC wound care lasted 24 days. Six of the seven patients had lower extremity lesions vs one with lesions involving the abdomen. Inflammatory bowel disease was noted in two patients, one with malignant melanoma, and another with psoriasis. Corticosteroids were begun 1.75 days after admission for six of the seven patients. Of the seven PG patients, five had excision and/or skin grafting with vacuum-assisted wound closure used in four. Six patients were discharged, but one patient succumbed early to sepsis. Skin grafting often speeds up chronic wound closure; however for PG this causes progression of lesions. Persistent non-healing wounds with pain disproportionate to size may be PG. Prompt diagnosis and BTC specialized care greatly improve outcomes for PG patients.
