Mycobacterium abscessus infection in a spa worker

Area of Science:

• Medical Microbiology
• Dermatology
• Infectious Diseases

Background:

• Mycobacterium abscessus (M. abscessus), a non-tuberculous mycobacterium, is increasingly recognized as a human pathogen.
• This bacterium is ubiquitous in the natural environment, posing a risk for infection through various exposure routes.

Observation:

• A case of a skin ulcer caused by M. abscessus in a spa worker is presented.
• Contamination often occurs via tap water, though outbreak sources remain frequently unidentified.
• Cutaneous ulcers, particularly in trauma-prone areas, necessitate considering non-tuberculous mycobacterial infections in differential diagnoses.

Findings:

• Early diagnosis of M. abscessus skin infections relies on biopsies and mycobacterium cultures.
• No standardized treatment exists for M. abscessus skin infections; management is individualized based on host immunity and disease severity.

Implications:

• Highlights the importance of considering M. abscessus in the differential diagnosis of unexplained cutaneous ulcers.
• Emphasizes the need for prompt microbiological investigation for effective patient management.
• Suggests potential environmental sources, such as tap water, in M. abscessus outbreaks.
