Mucormycosis in transplant patients

Area of Science:

• Mycology
• Transplant Surgery
• Infectious Diseases

Background:

• Renal transplant recipients are immunocompromised, increasing susceptibility to opportunistic infections.
• Mucormycosis is a rare but severe fungal infection, particularly in immunocompromised individuals.
• Nosocomial infections pose a significant risk in healthcare settings, especially for vulnerable patient populations.

Observation:

• A case of cutaneous mucormycosis developed at an internal jugular cannula site in a renal transplant recipient.
• The infection presented as gangrenous cellulitis of the neck.
• Histological confirmation and fungal cultures identified the causative agent as Mucor sp.

Findings:

• This represents a rare instance of cutaneous mucormycosis in a renal transplant patient, with only one previous cutaneous case reported in this population.
• The infection originated at an intravenous cannula site, a rare occurrence for mucormycosis, with only one prior reported case in a diabetic patient.
• Despite aggressive management including surgical debridement and amphotericin B, the patient succumbed to the infection.

Implications:

• This case highlights the critical need for vigilance regarding rare opportunistic infections in renal transplant recipients.
• Early recognition and prompt intervention are crucial for managing invasive fungal infections like mucormycosis in immunocompromised hosts.
• The occurrence at an intravenous cannula site underscores the importance of strict aseptic techniques and surveillance for nosocomial infections in transplant care.
