The authors report a new case of signet ring cell carcinoma of bladder whose characteristic findings are the parietal infiltration and the rapidly fatal course. Based on a review of the literature, they define the histological features of this very rare tumour (less than 20 documented cases have been reported). The pluripotent behaviour of urothelial cells appears to be the essential element in the histogenesis of this tumour type, which is very similar to gastric linitis plastica.
作者报告了一例膀胱印戒细胞癌新病例，其特征性表现为壁层浸润和快速致死病程。基于文献回顾，他们明确了这种极为罕见肿瘤（已报道的病例不足20例）的组织学特征。尿路上皮细胞的多能性行为似乎是这种肿瘤类型组织发生的关键要素，该肿瘤与胃皮革胃非常相似。
