Infections cutanées causées par des mycobactéries à croissance rapide [Skin infections due to rapid-growing mycobacteria].

Rapid-growing mycobacteria (e.g. M. abscessus and M. chelonae) are emerging pathogens with various clinical manifestations. Among immunocompetent individuals, rapid-growing mycobacteria may be responsible of pulmonary, cutaneous, osteoarticular and postoperative infections, as well as lymphadenitis and catheter-associated infections. Among immunocompromised patients, disseminated infections are also observed. Diagnosis relies on specific microbiological investigations to confirm etiology and guide antibiotic treatment. The treatment requires a multi-disciplinary approach that includes specific long-term antibiotic treatment, surgical debridement and reduction of immunosuppression whenever possible.
