Urinary bladder tumors in cats, unlike in dogs, usually localize outside of the trigonal region. These tumors are confused with urinary tract infections as both are associated with hematuria clinically. Cytological examination and ultrasound (USG) imaging techniques are very valuable, but histopatho- logical approach is the golden key. In this case neutered male, mix breed, 17-year-old cat was brought to the clinic with non-obstructive hematuria episodes. A superficial hypoechoic mass located at the apex of the urinary bladder was detected in the USG imaging technique. No discernible findings were found by cytological examination. After surgical removal of the suspected area, the biopsy specimen was presented to the pathology department for histopathological examination. Histopathological ex- amination revealed transitional cells covering entire surface of the mucosal epithelium and showing growth into the lumen, and they were characterized by mild anisocytosis and anisokaryosis. The pa- tient was diagnosed as in-situ non-papillary, non-infiltrating type of transitonal cell carcinoma (in-situ carcioma). These tumors are quite rare and have better prognosis. The condition of the patient was completely resolved without any extra medical treatment in postoperative period. When the poster was prepared, 6 months after the surgery, there was no recurrence in the patient. Contrary to infil- trative urinary bladder tumors, in-situ carcinoma could be completely cured surgically, therefore the case was found worthy to be presented.
