The dog was imported from the Bahamas at 3.5 y of age and had a history of transmissible venereal tumor (TVT) of the vulva that was successfully treated with a course of vincristine chemotherapy. Complete remission was achieved with a disease-free interval of 6 mo before clinical signs recurred. Abdominal ultrasound and CT scan identified a large caudal abdominal mass thought to arise from the uterine stump. An exploratory laparotomy was performed and the mass grossly excised. Histopathology was consistent with a poorly differentiated round cell tumor, and immunohistochemical analysis confirmed TVT as the most likely diagnosis. No further treatment was carried out. Repeat abdominal ultrasound at 4 mo after surgery showed no evidence of mass recurrence. At 8 mo after surgery, the dog was reported to be doing well clinically. Key clinical message: Transmissible venereal tumor should be considered as a differential diagnosis for masses arising from the deep genital tissues of dogs in cases where there is a history of previous TVT. Transmissible venereal tumor should be considered even in dogs that have had complete resolution of a primary mass after chemotherapy.</p>","PeriodicalId":9429,"journal":{"name":"Canadian Veterinary Journal-revue Veterinaire Canadienne","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11195512/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141475976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
