The transitional cell carcinoma of urinary bladder in dog: Case report

Abstract

The transitional cell carcinoma (TCC) is the most common bladder neoplasia in dogs. It's more frequent in elderly female ones and represents 75-90% of the bladder epithelial tumors. It generally occurs in the vesical trigone, therefore the treatment is palliative. Its etiology can be considered multifactorial and among the clinical signs are hematuria, polyuria and dysuria - which can be wrongly diagnosed as urinary infection as those are typical signs of this disease. The definitive diagnosis can only be considered after the histopathological analysis' result, however the ultrasonography exams, for example, can detect a neoplasia suspicion. The prognostic for neoplasia is bad, since it has a low potential for cure and a high level of mortality, so that it arises great interest in finding new possible ways of prevention, early diagnosis and new treatments. The present work aims to report a case of a dog with TCC, exposing how the definitive diagnosis was done by the histopathological exam after a bladder partial cystectomy, and its chemotherapy sessions with carboplatin associated with the continued use of piroxicam treatment. Unfortunately after two sessions the owner became absent, making it impossible to continue with the treatment.
