Ocular Candida with pale-centered hemorrhages
Abstract:
A 54-year-old man with severe thermal burns had Candida corneal ulcers and Candida septicemia develop, and he died 39 days after admission to the hospital. At autopsy examination, fungi were noted in the cornea to extend across the intact Descemet's membrane and were also found within foci of retinitis and choroiditis. Also, hemorrhages (some of which had pale centers) were present in both retinas. Histopathologic examination of these hemorrhages disclosed that the pale centers were comprised of a disrupted small blood vessel surrounded by an acellular material that most likely represented fibrin-platelet aggregates.
Insights
A severe burn patient developed Candida infections in the cornea and bloodstream, leading to death. Autopsy revealed fungal invasion of the cornea and eye tissues, alongside retinal hemorrhages.
Area of Science:
- Ophthalmology
- Mycology
- Pathology
Background:
- Severe thermal burns can compromise the immune system, increasing susceptibility to opportunistic infections.
- Candida species are common causes of opportunistic infections, particularly in immunocompromised individuals.
Observation:
- A 54-year-old male with severe thermal burns developed Candida corneal ulcers and septicemia.
- Fungal elements were observed in the cornea, extending across Descemet's membrane.
- Autopsy revealed fungal presence in foci of retinitis and choroiditis, with associated retinal hemorrhages.
Findings:
- Histopathology of retinal hemorrhages showed disrupted small blood vessels with fibrin-platelet aggregates.
- The findings suggest a potential mechanism for ocular and systemic dissemination of Candida in severely burned patients.
Implications:
- This case highlights the aggressive nature of Candida infections in severely immunocompromised patients.
- Understanding the pathological mechanisms of fungal dissemination is crucial for developing targeted therapies.
- Early recognition and treatment of fungal keratitis and septicemia are critical for improving patient outcomes.
