Abstract

More than 90% of bladder cancers are transitional cell carcinomas. Transitional cell carcinoma of the urinary bladder ordinarily does not pose diagnostic difficulties and is well known its clinical behavior. However, variation from the classic histology can cause problems in recognition. Recently several variants of transitional cell carcinoma of the urinary bladder have been described to promote the recognition of, or to draw attention to, possible differences in clinical behavior. The presence of a micropapillary component in transitional cell carcinoma is associated with high-stage and high-grade transitional cell carcinoma with a tendency of vascular invasion, and with poor prognostic histologic feature. We report a case of micropapillary transitional cell carcinoma of the urinary bladder.
