RESUMEN
Mycobacterium fortuitum causes a wide spectrum of cutaneous and extracutaneous diseases. Trauma may precede the primary cutaneous disease. Granulomatous nodules, ulcers, scrofuloderma, abscess, and sporotrichoid lesions have been described. Extracutaneous manifestations include postoperative vasculitis, endocarditis, pericarditis, mediastinitis, osteomyelitis, and disseminated disease. However, there have been few reports of scrofuloderma caused by M. fortuitum in the literature. We report a case of scrofuloderma due to M. fortuitum, which developed on the right inguinal area in a 8-year old boy. He had received a tearing injury to his gluteal region in a swimming pool. M. fortuitum was isolated by culture of skin specimen on Lowenstein- Jensen medium and subsequently identified by selected biochemical tests and comparative sequence analysis of rpoB gene (306 bp). Eight-week treatment with tetracycline after incision and drainage along with infrared irradiation resulted in complete resolution of the lesion.
