Urinary bladder tumors in cats, unlike in dogs, usually appear outside of the trigonal region as localization. These tumors are confused with urinary tract infections associated with hematuria in a clinical sense. Cytological examination and ultrasound (USG) imaging techniques are very valuable, but histopathological approach is the golden key. In this case neutered male, mixed, 17-year-old cat was brought to the clinic with non-obstructive hematuria attacks. 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 removal of the suspected area, the biopsy specimen was presented to the pathology department for histopathological examination. Histopathological examination 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 patient was diagnosed as in-situ non-papillary, non-infiltrating type of transitional cell carcinoma (in-situ carcioma). These tumors are quite rare and have better prognosis. The condition of the patient was completely resolved without medical treatment in the postoperative period. When this case report was prepared, 6 months after the operation, there was no recurrence in the patient. Contrary to infiltrative urinary bladder tumors, in-situ carcinoma could be completely cured by surgically, therefore the case was found worthy to be presented.
