Abstract
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.关键词
