Background: Prostatic cancer is a rare condition in cats but should be included as a differential diagnosis whenever middleaged cats present lower urinary tract signs, such as dysuria and hematuria. Abdominal ultrasound can indicate the disease,but fine-needle aspiration cytology and histopathology are necessary to establish the neoplastic origin and the therapeuticplan. Because of the limited data, no standard-of-care treatment or prognostic information exists in cats with prostate carcinoma. This report describes the clinical signs, diagnosis and surgical approach in a case of prostatic carcinoma in a cat.Case: A 6-year-old, intact male, domestic short-haired cat was presented with a 3-day history of dysuria, hematuria, inappetence, constipation, lethargy and prostration. On physical examination, the cat was in a very poor general conditionand abdominal palpation revealed firm mass located caudally to the urinary bladder. The urinary bladder presented highrepletion degree, while the large bowel was distended and presented soft faecal content. Blood count, serum biochemistryand urinalysis showed neutrophilic leukocytosis, hypoalbuminemia and high creatinine level, and severe hematuria, respectively. Abdominal ultrasound showed a mass located in the prostatic area with hypoechogenic and slightly heterogeneousparenchyma, measuring 3.3 x 3.0 cm. Echo-guided trans-abdominal fine-needle aspiration of the prostate was performed.Microscopically, the cells were round with basophilic cytoplasm, and had round to ovoid nuclei, dense chromatin andprominent nucleoli. Some cells were binucleated and mild anisocytosis and marked anisokaryosis were documented. Thesefindings were compatible with malignant prostatic neoplasia. After initial clinical stabilization, the patient underwent anexploratory laparotomy for tumor resection...(AU)
