A Case of Necrotizing Fasciitis due to Group G Streptococcus with Amputation Avoided of the Affected Limb

Group G Streptococcus (GGS) causes toxic shock syndrome. Its incidence has been increasing in the elderly in recent years. The case is a female patient in her 60s, with rheumatoid arthritis, who developed necrotizing fasciitis in her right thigh. We administered antibacterial agents and debridement frequently at an early stage, followed by aggressive high-protein enteral nutrition and multidisciplinary treatment. During the course of treatment, the patient’s general condition temporarily deteriorated because of fecal contamination. We considered amputation of the lower limb and implantation of a stoma, but finally succeeded in preserving the limb by performing two skin grafts. The patient was able to walk and was discharged on day 66. GGS infection is a risk factor for elderly patients with underlying diseases such as malignancy or immunocompromised states. When necrotizing fasciitis due to fulminant streptococcal infection develops in a proximal limb, amputation of the limb is often necessary to save the patient’s life. In this case, a fulminant GGS infection developed in an immunocompromised patient with active rheumatoid arthritis. Although the risk of limb amputation was high, multidisciplinary treatment enabled functional preservation of the affected limb.
