Summary
A dog with chronic nasal issues was diagnosed with intranasal malignant melanoma. Surgical removal and radiation therapy were used for treatment, marking a first for this condition in dogs.
Area of Science:
- Veterinary Medicine
- Oncology
- Canine Health
Background:
- Intranasal tumors are a concern in canine patients.
- Malignant melanoma, while common in other locations, is less frequently reported within the nasal cavity.
Observation:
- A 10-year-old female Newfoundland-cross dog presented with chronic unilateral epistaxis, nasal stertor, and sneezing.
- Nasal magnetic resonance imaging identified a significant mass (3 x 5 cm) in the left nasal cavity.
Findings:
- Histopathological examination of nasal biopsies confirmed the mass as a malignant melanoma.
- The canine intranasal malignant melanoma was surgically resected.
- Post-operative treatment included bilateral opposed photon-beam radiation therapy.
Implications:
- This case represents the first documented instance of intranasal malignant melanoma in a dog.
- Highlights the importance of diagnostic imaging and histopathology for nasal masses.
- Provides a potential treatment protocol for future canine intranasal melanoma cases.
