Skin and wound infection by rapidly growing mycobacteria - An unexpected complication of liposuction and liposculpture

Objective: To describe 10 patients with skin and soft tissue infection caus ed by rapidly growing mycobacteria after cosmetic liposuction and liposculp ture. Design: Case series. Settings: Eight private geographically separate surgical facilities from a single metropolitan area. Patients: Eight patients with definite and 2 with presumptive cases of skin and soft tissue infection caused by rapidly growing mycobacteria after cos metic surgery procedures during a 24-month period. Microorganisms were isol ated from the purulent drainage obtained from wounds or fistulas in 8 cases and were identified as Mycobacterium fortuitum (3 cases) and Mycobacterium abscessus (5 cases) by routine microbiologic techniques. Acid-fast bacilli were observed on Ziehl-Neelsen-stained smears in the 2 remaining cases, bu t these ultimately failed to grow. In 2 of the surgical units, no apparent environmental predisposing factors were identified after thorough microbiol ogic environmental investigation. Clinically, all patients exhibited signs of inflammation, microabscesses, and purulent wound drainage within 24 mont hs of abdominal and/or thigh liposuction or homologous fat tissue injection . Intervention: A combined therapeutic approach including surgical drainage, debridment, and prolonged (>3 months) treatment with combined antimicrobial agents including clarithromycin was used in all cases. Results: Nine of 10 patients responded to the combined therapeutic approach , and no evidence of infection was present during at least 12 months of fol low-up. Conclusion: To our knowledge, this is the first series of patients with rap idly growing mycobacterial infections to be described after liposuction and liposculpture. Rapidly growing mycobacteria should be included in the diff erential diagnosis of skin and soft tissue infection after cosmetic surgery .
