Urothelial neoplasm of pelvis renalis with cytomorphology findings [Sitomorfolojik bulgularla pelvis renalisin üroteryal neoplazmi]

Urine cytology is an important diagnostic technique for urothelial neoplasia. Although it is difficult to demonstrate the cytopathological clues in the diagnos are of pelvicalicial system and urothelial tumors, tumor grading and diagnosis with cytology provides important advantages for treatment. After "right pelvis renalis tumor?" determination in abdominal computerized tomography of a 55 year old male patient for gross hematuria etiology search, multiple milimetric papillary mass appearance was observed at pelvis renalis in ureterorenoscopy. In examination of urine sample obtained during this procedure reported as "suspicious of malignancy". A tumoral mass characterized with papillary structures composed of 6-7 epithelial cells layer lined around fibrovasculary core, is designated in cross sections. Tumor was composed of atypical epithelial cells with pleomorphic, coarse, apparent nucleoli, hyperchromatic nuclei and eosynophilic cytoplasm features. Tumor with no lamina propria invasion reported as "papillary urothelial neoplasm with low malignancy potential (WHO/ISSUP 98)" Our case was worth presentation because of its diagnostic cytological features. © 2009 OMÜ Tüm Haklari Saklidir
