Summary
Dermatophytic pseudomycetoma, a deep fungal infection, was diagnosed in two ferrets. This rare condition, caused by Microsporum canis and Trichophyton sp., presents as cutaneous nodules.
Area of Science:
- Veterinary Mycology
- Dermatopathology
- Exotic Animal Medicine
Background:
- Dermatophytic pseudomycetoma is a rare, deep-seated fungal infection affecting dermal and subcutaneous tissues.
- Typically associated with Microsporum canis or Trichophyton species, it has been documented in cats, dogs, and horses.
Observation:
- This case report details two domestic ferrets (Mustela putorius furo) presenting with dermatophytic pseudomycetoma.
- Clinical signs included multiple firm cutaneous nodules ranging from 0.6 to 3 cm in diameter.
Findings:
- Diagnosis was confirmed via histological examination and fungal culture.
- Microscopic analysis revealed multifocal nodular pyogranulomatous inflammation with intralesional fungal elements in both ferrets.
Implications:
- This study represents the first documented instance of dermatophytic pseudomycetoma in domestic ferrets.
- Clinicians should consider this fungal infection in the differential diagnosis for nodular skin conditions in ferrets.
