Background
- Atypical Mycobacterium species found in fresh or salt water (cold or warm)
- Bacteria that causes "fish tank Granuloma"
- Can infect both immunocompetent and immunocompromised hosts
- M. marinum is generally not found in chlorinated swimming pools[1]
Risk Factors
- Aquarium workers and enthusiasts
- Swimming
- Handling of contaminated water
Clinical Features
Fish tank granuloma. [2]
- Solitary to multiple superficial red nodules or plaques in exposed areas
- Lesions on the hands and fingers if works with aquariums, or the knees and elbows in swimmers
- Ascending lymphangitis that resembles sporotrichosis
Differential Diagnosis
Skin and Soft Tissue Infection
- Cellulitis
- Erysipelas
- Lymphangitis
- Folliculitis
- Hidradenitis suppurativa
- Skin abscess
- Necrotizing soft tissue infections
- Mycobacterium marinum
Look-A-Likes
- Sporotrichosis
- Osteomyelitis
- Deep venous thrombosis
- Pyomyositis
- Purple glove syndrome
- Tuberculosis (tuberculous inflammation of the skin)
Evaluation
- Clinical diagnosis in ED
- Can be aided by histopathology
- If there is an affected joint it is important to evaluate for a septic arthritis
- If there are draining wounds consider imaging and evaluate for osteomyelitis
Management
- Long-term antibiotic therapy (2-18 weeks)
- Monotherapy with doxycycline, clarithromycin, bactrim, or minocycline[3][4]
- Secondary to drug high levels of drug resistance, may require dual drug therapy
- Warm compresses (bacterium is heat-sensitive)
Disposition
- Unless the patient has evidence of sepsis, severe pain, or has other severe complicating medical problems, outpatient treatment is acceptable.
Clinical Course
- M marinum infection may result in non-healing ulcers or a septic arthritis.
- Aggressive or long standing . marinum infection may cause severe osteomyelitis requiring surgical debreedment
