<B><I>Background</I>:</B> The micropapillary variant of transitional cell carcinoma is a recently described, aggressive urinary bladder cancer. Whose cytologic features are not well known.<BR><B><I>Cases</I>:</B> We report two cases of this bladder cancer confirmed by histology. Case 1: A 67-year-old woman admitted for a pelvic tumor and undergoing tumorectomy under a diagnosis of malignancy of unknown origin was found in pathologic examination to have advanced bladder cancer with extensive invasion of surrounding organs. Case 2: A 72-year-old man treated by transurethral resection for a papillary bladder tumor underwent total cystectomy 5 month later due to positive cytological and histological studies. A recurrent tumor was found in the rectum after one year. Preoperative cytological studies of both cases showed tight-cohesive papillary clusters of middle to large tumor cells with marked atypical nuclei.<BR><B><I>Conclusion</I>:</B> The poor prognosis of this rare variant makes its recognition in urinary cytology extremely important.
