Mycobacterium abscessus infection in a spa worker.

Mycobacterium abscessus (M. abscessus) is a non-tuberculous mycobacterium widely present in the natural environment and is now being increasingly identified as a cause of human disease. However, it can cause skin and soft tissue infection following trauma or surgery. We report a case of a skin ulcer associated with M. abscessus in a spa worker. Frequently, contamination with atypical mycobacteria occurs through tap water. However, in most outbreaks the infection source remains unknown. For an early diagnosis, it is important to perform biopsies and mycobacterium cultures. No specific treatment for skin infection with M. abscessus has been established; it depends on the immune status of the host and the extent of disease. Although it is rare, non-tuberculous mycobacterial infection should be part of the differential diagnosis of cutaneous ulcers, especially on trauma-prone areas.
