摘　　要：Objective： To study the pathologic features of plasmacytoid transitional cell carcinoma of the bladder, and to analyze the diagnostic features, criteria for differential diagnosis and the clinical significance of the tumor. Methods： Two cases of bladder plasmacytoid transitional cell carcinoma were studied. Routine paraffin sections with HE staining, Pap smear and immunohistochemistry by S-P method were observed under a light microscope. Pathological and clinical data were analyzed by comparison with early reported cases in literatures. Results： A characteristic feature of this tumor was of deep invasion in the lamina propria and/or muscularis propria, in addition to the component of carcinoma in situ in the mucosa, when tumors were diagnosed. The histological pattern and cytological features showed similarity to a plasmacytoid tumor. The tumor cells were strongly positive for AE1/AE3, CEA and CK18. The prognosis appeared to be worse than ordinary transitional cell carcinoma. Conclusion： The plasmacytoid transitional cell carcinoma of bladder is rare but has typical pathological, immunohistological and clinical features. Pathologists should be aware of this kind of primary tumor of bladder.
