Summary
This case study highlights streptococcal gangrene in an AIDS patient, a rare occurrence. Early diagnosis of this severe orbital infection is critical for managing vision loss and systemic illness.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Dermatology
Background:
- Streptococcal gangrene typically affects healthy individuals.
- Orbital cellulitis can lead to severe vision impairment and systemic illness.
- Prior reports have not documented streptococcal gangrene in HIV-infected patients.
Purpose of the Study:
- To report a rare case of streptococcal gangrene involving the eyelids and orbit in a patient with Acquired Immunodeficiency Syndrome (AIDS).
- To emphasize the importance of early diagnosis and recognition of specific clinical signs.
Main Methods:
- Case study of a patient with AIDS presenting with orbital cellulitis.
- Clinical examination, surgical debridement, intravenous antibiotic therapy.
- Histopathological examination of the lesion and microbial cultures.
Main Results:
- The patient presented with fulminant orbital cellulitis due to Group A beta-hemolytic Streptococcus.
- Histopathology revealed extensive soft tissue necrosis and vascular thrombosis.
- Treatment included debridement and antibiotics, with partial improvement except for visual function.
Conclusions:
- Streptococcal gangrene can occur in patients with HIV/AIDS, despite its rarity.
- Early recognition of cutaneous, histopathological, and anterior segment ischemia signs is crucial for prompt diagnosis and management.
- This condition poses a significant risk of vision loss and systemic complications.
