    Author: Saracino A, Kelly R, Liew D, Chong A.
    Journal: Australas J Dermatol; 2011 Aug; 52(3):218-21. PubMed ID: 21834821.
    Abstract:
    We present a case series of inpatients with pyoderma gangrenosum (PG), an ulcerative neutrophilic skin condition of unknown aetiology. Twenty-six patients were admitted with PG, nine men and 17 women. At the time of the chart review, seven patients (26.9%) had died. Patients had a mean of 2.0 active ulcerative lesions and 22 patients' ulcers (84.6%) were on the lower limb. Systemic diseases were coexistent in 15 patients (57.7%), the most common being rheumatoid arthritis (19.2%). Thirty-eight wound cultures were taken and were positive for Staphylococcus aureus in 22 cases (57.8%) and Pseudomonas aeruginosa in 20 (52.6%). After prednisolone, cyclosporin was the next most commonly prescribed systemic therapy (34.6%). Surgical debridement was undertaken in seven cases (26.9%) and two patients had skin grafts. Upon discharge from hospital, 21 patients' ulcers (80.8%) had improved. At 6 months 50% showed complete ulcer healing. Our results highlight the potential severity of PG requiring hospital admission, the need for aggressive therapy and the overall high associated morbidity and mortality.
