Adenokarzinom in der Harnblase einer männlichen Fischkatze ( Prionailurus viverrinus Benett, 1833)

Abstract

A 12-year-old male fishing cat ( Prionailurus viverrinus) was presented with apathia, haematuria and dysuria-stranguria. The clinical examination revealed a firm mass in the caudal abdomen. Blood- and urinanalysis were performed as well as X-rays and sonography, which showed a mass in the bladder and free fluid in the abdominal cavity. Subsequent laparotomy revealed a tumor protruding from the wall of the bladder and a small perforation. Furthermore, firm nodules in the stomach wall, omentum and ileosacral lymphnodes were detected. Due to the age of the cat and invasiveness of the tumor euthanasia was elected. The histopathological diagnosis was: invasive adenocarcinoma of the bladder, stomach, omentum and metastases in the ileosacral lymphnodes. In contrast to the rare bladder tumors in domestic cats, there are several reports on transitional cell tumors in fishing cats. But to the authors knowledge there are no reports on adenocarcinomas of the bladder.
