谢谢quhong老师，本病例伞细胞还存在，细胞异型性也不大，怎么不诊断具有恶性潜能的尿路上皮乳头状瘤呢？
新手上路，谢谢老师指点
The histologic differences between papillary neoplasms of low malignant potential and papillary carcinoma of low grade may be subtle. However, some cells within papillary low grade carcinoma are overtly neoplastic, whereas cells in tumors of low malignant potential lesions show at most only nuclear enlargement. Low grade papillary carcinomas may invade the lamina propria, and have a low (<5%) risk of further progression, although they frequently recur (The World Health Organization/International Society of Urological Pathology Consensus Classification of Urothelial (Transitional Cell) Neoplasms of the Urinary Bladder, The American Journal of Surgical Pathology Issue: Volume 22(12), December 1998, pp 1435-1448).
