Background:
Dermatophytic pseudomycetoma is an atypical form of dermatophytosis where the infection is located in the deep dermal and subcutaneous tissues. Although rare, it is most commonly associated with Microsporum canis or Trichophyton sp. It has been reported in cats, dogs and horses.
Objectives:
To describe the clinical and pathological findings of dermatophytic pseudomycetoma caused by M. canis and Trichophyton sp. in two domestic ferrets.
Animals:
Two pet ferrets (Mustela putorius furo).
Method And Materials:
Case report.
Results:
Two ferrets were diagnosed with dermatophytic pseudomycetoma confirmed by histological examination of tissue and fungal culture. In both cases, ferrets presented with several cutaneous firm nodules 0.6-3 cm in diameter. Microscopic lesions revealed multifocal nodular pyogranulomatous inflammation with intralesional fungi.
Conclusions And Clinical Importance:
To the best of the authors' knowledge, this is the first description of dermatophytic pseudomycetoma in domestic ferrets. This disease should be included in the differential diagnosis of nodular dermatopathies in this species.
Insights
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.
