A man developed hand nodules after Mycobacterium marinum infection treatment. This case highlights potential lingering infections from aquarium fish, even after antibiotic therapy.

Area of Science:

Dermatology
Infectious Diseases
Aquatic Medicine

Background:

Mycobacterium marinum infections, often acquired from aquatic environments, can cause skin lesions.
Treatment of M. marinum typically involves a combination of antibiotics, such as rifampin and clarithromycin.
Recurrence or persistent symptoms can occur despite appropriate antimicrobial therapy.

Observation:

A 49-year-old male patient presented with new nodules on his right hand.
The patient had a recent history of Mycobacterium marinum infection.
The infection was recently treated with rifampin and clarithromycin.
The patient owns an aquarium containing Betta fish.

Findings:

The development of nodules suggests a potential relapse or persistent Mycobacterium marinum infection.

Related Experiment Videos

The patient's exposure to Betta fish in an aquarium is a likely source of M. marinum.

Antibiotic treatment may not always fully eradicate the infection, necessitating further evaluation.

Implications:

This case underscores the importance of considering M. marinum in patients with hand lesions and aquatic exposure, even after initial treatment.
Aquarium owners should be educated about the risks of M. marinum infections and preventive measures.
Further investigation may be needed to determine the optimal duration and regimen for M. marinum treatment to prevent recurrence.
