Disseminated cutaneous atypical mycobacteriosis by M. chelonae after sclerotherapy of varicose veins in a immunocompetent patient: a case report*

Atypical mycobacteria are saprophytic organisms not transmitted from person to person, which affect mainly immunosuppressed but also immunocompetent individuals. We present a case of atypical mycobacteriosis after a vascular procedure, with widespread cutaneous lesions associated with polyarthralgia. Mycobacterium chelonae was identified by the polymerase chain reaction (PCR) method. The patient showed improvement after treatment with three antibiotics. Mycobacterium chelonae causes skin lesions after invasive procedures. The clinical form depends on the immune state of the host and on the entry points. The diagnosis is based essentially on culture and the mycobacteria is identified by PCR. We highlight the importance of investigating atypical mycobacteriosis when faced with granulomatous lesions associated with a history of invasive procedures.
