Abstract
A 30-year-old woman visited us with a large ulcer on the lower abdomen, which had appeared on the second day following a Caesarean operation. The ulcer was shallow, but exposed the subcutaneous fat tissue. The edge of the ulcer was edematous and was covered by necrotic tissue. Histopathological findings of specimens taken from the ulcer were non-specific. No pathogenic organisms were cultured from the materials of the ulcer. The ulcer epithelized in about 4 weeks with treatment. Though we could not obtain clear histopathological or bacteriological evidence, we concluded that the ulcer was a bacterial gangrene because of the numerous large gram-positive bacteria found in the histologic sections previously taken at Kyushu Kouseinenkin Hospital.
