Mycobacterium chelonae facial infections following injection of dermal filler

A cluster of 3 facial Mycobacterium chelonae infections occurred after cosmetic dermal filler injections at a plastic surgery clinic. Pulsed-field gel electrophoresis showed that M chelonae isolated from the clinic tap water were identical to the patient wound isolates. Review of injection procedures identified application of nonsterile ice to the skin prior to injection as a possible source of M chelonae. Surveys of regional laboratories and a national plastic surgery listserv identified no other cases related to the injection of this brand of dermal filler. This is the first report of cutaneous M chelonae infections following the injection of dermal fillers. It adds to a growing body of literature on postinjection M chelonae infections and reinforces the importance of optimal skin disinfection steps prior to percutaneous procedures.
