Cutaneous protothecosis in a patient receiving immunosuppressive therapy
Archives of Dermatology
|June 1, 1976
Summary
A renal transplant patient on immunosuppressive therapy developed Prototheca skin infections, highlighting a rare complication. This case underscores the risk of opportunistic infections in immunocompromised individuals.
Area of Science:
- Medical Mycology
- Infectious Diseases
- Transplantation Immunology
Background:
- Prototheca species are achloric algae, distinct from fungi and yeasts.
- Cutaneous protothecosis is a rare infection, with few reported cases since 1964.
- Immunosuppression is a potential risk factor for Prototheca infections.
Observation:
- A 30-year-old renal transplant recipient on immunosuppressive therapy presented with cutaneous abscesses.
- Cultures from skin lesions yielded Prototheca species.
- The patient ultimately succumbed to Klebsiella septicemia.
Findings:
- This case represents the second reported instance of cutaneous protothecosis in an immunosuppressed patient.
- Concurrent Candida infection was also noted in a separate skin lesion at the time of death.
- Prototheca and Candida are opportunistic pathogens that can cause severe infections in immunocompromised hosts.
Implications:
- This case highlights the importance of considering rare opportunistic infections like protothecosis in transplant recipients.
- Early diagnosis and management of Prototheca infections are crucial, though challenging.
- Further research is needed to understand the pathogenesis and optimal treatment strategies for protothecosis in immunosuppressed individuals.
