Soft tissue infections.

Soft tissue infections are common and potentially fatal conditions. Infections are a major cause of morbidity and mortality in patients who have rheumatic disease. Patients who have rheumatic diseases may be at increased risk for soft tissue infections because of various factors, including inherent immunologic defects, genetics, and use of immunomodulatory therapy, including biologic agents. Timely diagnosis and management with the institution of antibiotics with or without surgical intervention is imperative for effective resolution of infection. This article provides a review of recent literature on the presentation and clinical course of infectious tenosynovitis, septic bursitis, pyomyositis, and necrotizing fasciitis, especially in relation to patients who have rheumatic disease.
