Sporothricoid mycobacterial infection. A case report

Area of Science:

• Dermatology
• Infectious Diseases
• Microbiology

Background:

• Mycobacterium marinum infections, often acquired through aquatic exposure, can cause skin granulomas.
• Sporothricoid spread is a characteristic clinical presentation of certain mycobacterial infections.
• Chronic hand eczema may predispose individuals to skin infections.

Observation:

• A case of bilateral, symmetric sporothricoid granulomas on the fingers and wrists is presented.
• The infection was culture-proven as Mycobacterium marinum.
• The patient was a fish-fancier who acquired the infection while cleaning an aquarium bare-handed.

Findings:

• The patient presented with chronic hand eczema, potentially a risk factor for infection.
• The granulomas exhibited a sporothricoid pattern, consistent with Mycobacterium marinum infection.
• Co-trimoxazole therapy demonstrated successful resolution of the skin lesions.

Implications:

• This case underscores the importance of considering Mycobacterium marinum in fish-fanciers presenting with sporothricoid granulomas.
• Early diagnosis and appropriate antibiotic treatment, such as co-trimoxazole, are crucial for managing Mycobacterium marinum infections.
• Understanding risk factors like aquarium cleaning and pre-existing skin conditions aids in prevention and treatment strategies.
