摘要:
The clinical, microscopical, immunocytochemical and ultrastructural features of five cases of benign mesenchymal proliferative lesions of the urinary bladder, mimicking sarcoma, are presented. Four of the five patients are alive and disease‐free following diagnosis, an interval ranging from 9 months to 9 years, mean 4 years. A fifth patient, who had a pseudosarcomatous stromal response adjacent to a urinary transitional cell carcinoma, now has invasive transitional cell carcinoma. The lesions revealed a striking microscopical, immunocytochemical and ultrastructural similarity to nodular fasciitis, suggesting the lesions represented a bizarre mesenchymal proliferative response to inflammatio
