[Fatal retroperitoneal necrotizing fasciitis due to Aeromonas caviae septicaemia]

Area of Science:

• Microbiology
• Infectious Diseases
• Clinical Case Reports

Background:

• Aeromonas species are known pathogens causing gastrointestinal and wound infections.
• Severe Aeromonas infections, including necrotizing fasciitis, can be fatal, particularly in immunocompromised individuals.
• Gastric cancer and its treatments can increase susceptibility to opportunistic infections.

Observation:

• A previously unreported case of fatal retroperitoneal necrotizing fasciitis is presented.
• The infection was caused by Aeromonas caviae.
• The patient had a history of gastric cancer.

Findings:

• Aeromonas caviae was identified as the causative agent of retroperitoneal necrotizing fasciitis.
• The infection led to a fatal outcome despite medical intervention.
• This represents a rare and severe manifestation of Aeromonas infection.

Implications:

• This case underscores the potential for Aeromonas caviae to cause severe, life-threatening infections beyond typical presentations.
• Clinicians should maintain a high index of suspicion for invasive Aeromonas infections in immunocompromised patients, especially those with malignancy.
• Further research into the virulence factors and treatment strategies for invasive Aeromonas infections is warranted.
