Summary
A rare skin infection, primary cutaneous mucormycosis caused by Rhizopus oryzae, occurred in an immunocompetent patient after trauma. Prompt amphotericin B treatment successfully cured the infection.
Area of Science:
- Mycology
- Dermatology
- Infectious Diseases
Background:
- Primary cutaneous mucormycosis is a rare fungal infection.
- Mucormycosis typically affects immunocompromised individuals.
Observation:
- An immunocompetent patient with a history of trauma presented with encrusted erythematous plaques and pustules on the shin.
- The lesions were consistent with a fungal infection following skin abrasion.
Findings:
- Histopathology confirmed Rhizopus oryzae as the causative agent.
- Microscopic examination revealed characteristic broad, non-septate hyphae with right-angle branching in the dermis, indicative of mucormycosis.
- The infection demonstrated widespread granulomatous inflammation.
Implications:
- This case highlights that primary cutaneous mucormycosis can occur in immunocompetent individuals following trauma.
- Early diagnosis and treatment with intravenous amphotericin B are crucial for successful outcomes.
- Understanding the clinical presentation and histopathological features is essential for managing this rare fungal infection.
