国外文献报道9例：Ro JY, Shen SS et al. Plasmacytoid transitional cell carcinoma of urinary bladder: a clinicopathologic study of 9 cases. Am J Surg Pathol.2008 32:752-7.

In this report, we summarized the clinicopathologic features of 9 cases of plasmacytoid transitional cell carcinoma (TCC) of the urinary bladder, a rare variant of TCC. One patient had TNM stage I disease, 2 had stage II disease, 3 had stage III disease, and 3 had stage IV disease. Microscopically, all tumors contained plasmacytoid cells, which composed 30% to 100% of the entire tumor. Eight of 9 cases were associated with high-grade TCC. The plasmacytoid tumor cells were characterized by eccentrically located nuclei and abundant eosinophilic cytoplasm. Five patients died of disease from 5 to 36 months. In summary, plasmacytoid TCC tends to present at an advanced stage and to have a poor prognosis. Morphologic recognition and distinction from other plasmacytoid malignant neoplasms is critical for its clinical management and immunohistochemical studies may be required for differential diagnosis.
