A Suspected Case of Cutaneous Mycobacterium immunogenum Infection / 나학회지

ABSTRACT

M. immunogenum was identified as the etiologic agent of a variety of hospital-acquired infections, including an outbreak of keratitis, and as the potential cause of hypersensitivity pneumonitis in industrial metal-grinding machinists. This microorganism appears to differ from other members of the M. chelonae?abscessus group. Clinically significant isolates have been recovered from skin lesions, corneal ulcers, joint fluid, central venous catheter sites, and blood. There have been some cases of M. immunogenum skin infection reported. We report a suspected case of cutaneous Mycobacterium immunogenum infection in a 23-year-old male, migrant Workers from Sri Lanka, who presented with an erythematous plaque on his right ear. M. immunogenum was suspected by PCR-restriction fragment length polymorphism & sequencing of PCR product. The patient was treated with clarithromycin & ofloxacin. The lesion started to improve 4 weeks after initiation of the therapy. We have the patient in therapy for 3 months, and the lesion is slowing disappeared.
