Chronic granulomatous infection of the skin and soft tissue by nontuberculous mycobacteria in patients with normal immune system is rarely reported. This case was about a child patient, with normal immune system, whose lower leg was lacerated after a slip down in the Philippines and it was previously treated at a hospital in the Philippines. After a couple of surgical debridement of the wound, the cause of the soft tissue infection was found to be a combined infection of nontuberculous mycobacteria and mycobacterium tuberculosis. We present a case that has been rare in Korea, but common overseas.
