Successful diagnosis and treatment of nasal transmissible venereal tumour in a dog

Summary

Transmissible venereal tumour is a canine‐specific, round cell neoplasm typically transmitted through direct contact, primarily affecting genital lesions. Nasal transmissible venereal tumour is rare in dogs and can be presented with nonspecific signs. The objective of the present study was to report a complicated chronic case of nasal transmissible venereal tumour in a 4‐year‐old male Indian Spitz dog. The dog was presented with a history of epistaxis and snoring at different intervals. For differentials, haemoprotozoan infections, nasal polyp, fungal infection and coagulation disorders were considered. The histopathological examination of a detached tissue mass expelled from the nasal cavity during forceful sneezing confirmed it to be a nasal transmissible venereal tumour. This case highlights the importance of considering a broad differential diagnosis, including nasal transmissible venereal tumour, when faced with atypical presentations such as epistaxis and snoring in dogs. Vincristine chemotherapy proved an effective treatment for nasal transmissible venereal tumour, leading to a favourable clinical outcome.
