[Mycobacterium fortuitum skin infection occurring after a facelift]

Abstract

Introduction: Mycobacterium fortuitum skin infections are rare and usually iatrogenic. We report a case with cervical involvement following a facelift.

Observation: A 65 year-old woman, without past history, underwent bilateral surgical facelift, complicated by cutaneous necrosis and treated with directed healing at home. Six weeks later, an abscessed nodule appeared under the left maxillary and was drained surgically. Then other pre-auricular and left cervical inflammatory nodules appeared without adenopathy or fever. M. fortuitum was isolated in bacteriological samples. The initially probabilistic antibiotherapy with carithromycin, subsequently adapted with amikacine and cirprofloxacine and then imipeneme for a total duration of 3 months, led to the clinical cure.

Discussion: Mycobacterium fortuitum is a rapidly growing, ubiquitous, mycobacteria responsible for nosocomial infections in immunocompetent patients, notably following plastic surgery. Contamination occurs where there has been a rupture in the skin barrier through contact with a vector (water, surgical material, antiseptic.). Treatment, which is not codified, consists in the association of surgery and antibiotics for several months.
