Abstract
We report a case of necrotizing fasciitis caused by group G streptococci. A 76-year-old man had swelling of his left foot and fever. On arrival, he presented with swelling and redness localized to the distal end of his left ankle. The swelling and redness spread immediately, and vacuoles and cutaneous necrosis appeared. The patient's condition was diagnosed as necrotizing fasciitis, for which he was treated with broad-spectrum antibiotics from day 1. On day 2 after admission, the necrotic tissue from his left leg was debrided. Serous pus obtained from the necrotized tissue and the vacuoles showed growth of group G Streptococcus dysgalactiae subsp. equisimilis. Subsequently, we changed the antibiotics to ampicillin. Skin grafts were placed 43 days and 92 days after admission. His condition improved, and he was discharged from the hospital on day 111. In recent years, the incidence of necrotizing fasciitis caused not only by group A streptococci but also by group G streptococci has increased. Thus, we require appropriate antibiotics and debridement to treat such patients.
