Plain-English summary
This case involves a dog with a long nose, likely between 10 to 15 years old, who had a problem with bloody discharge from its nose that kept coming back. After several tests, including blood work and imaging scans, the dog was diagnosed with nasal squamous cell carcinoma, a type of cancer in the nose. The treatment included surgery to remove the tumor and chemotherapy over a period of 21 weeks. However, when the bloody discharge returned after treatment, the veterinarians performed a procedure to help open up the nasal passage again. Overall, the treatment did not fully resolve the issue, as the nasal discharge came back.
Abstract
Nasal tumors in dogs are most frequently found in long-nosed breeds aged 10 to 15 years, especially among urban dogs. This case report describes a dog with recurrent bloody nasal discharge. Diagnostic tests, including laboratory analysis, CT, MRI, and histopathology, confirmed the diagnosis of nasal squamous cell carcinoma. The dog was treated with surgical resection and chemotherapy over 21 weeks. At the 21-week follow-up, nasal discharge had returned, prompting external carotid artery ligation, which reopened the nasopharynx.
