- Includes Fonsecaea pedrosoi (most common), F. monophora, F. nubica
Clinical Manifestations
- Most common agent causing human chromoblastomycosis
- Infection likely occurs as a result of direct traumatic inoculation of plant debris into a wound i.e. coconut shells
- Chronic localized fungal infection of the skin and subcutaneous tissue that produces raised, scaly lesions, usually in the lower extremities
- Lesions are warty, cauliflower-like
Diagnosis
- Culture
- Microscopy:
- Septate hyphae with poorly formed cylindrical conidiophores producing short chains of conidia
- Pathognomonic muriform cells (copper penny) found on histology
Management
- Surgery + itraconazole + terbinafine for severe cases has been suggested
