Summary
This summary is machine-generated.

We present two cases of primary cutaneous mucormycosis in immunocompromised individuals. Diagnostic histopathology revealed characteristic fungal elements, including a unique epidermal finding in one patient.

Area of Science:

  • Mycology
  • Dermatology
  • Infectious Diseases

Background:

  • Primary cutaneous mucormycosis is a rare fungal infection.
  • It primarily affects immunocompromised patients, often presenting with non-specific skin lesions.
  • Early diagnosis is crucial for effective management.

Observation:

  • Two cases of primary cutaneous mucormycosis in immunocompromised patients were analyzed.
  • Clinical presentation included non-specific necrotic ulcers.
  • Histopathological examination was key to diagnosis.

Findings:

  • Broad, branching, nonseptate hyphae, characteristic of Mucorales, were identified in the dermis and subcutaneous tissue of both patients.
  • In one unique case, fungal hyphae were also detected within the epidermis.

  • This represents the first reported instance of epidermal hyphae in primary cutaneous mucormycosis.

    • Implications:

    • The histopathological identification of fungal hyphae is critical for diagnosing cutaneous mucormycosis, even with non-specific clinical signs.
    • The presence of hyphae in the epidermis, though rare, may offer insights into fungal invasion patterns.
    • Further research into the diagnostic markers and pathogenic mechanisms of cutaneous mucormycosis is warranted.
