PURPOSE: Bladder @entity189 is an invasive @entity189 subtype that is emphasized for its morphological overlap with plasma cells and @entity189 . Our experience suggests frequent intraperitoneal spread that is not typical of conventional @entity189 . MATERIALS AND METHODS: We identified cases of plasmacytoid @entity189 diagnosed on radical cystectomy. @entity1 age, gender, American Joint Committee on @entity5 (7th edition) stage, metastatic spread/recurrence sites and clinical disease status at last followup were recorded. RESULTS: A total of 10 male and 5 female @entity1 42 to 81 years old were identified. One @entity5 was pT2, 11 pT3 and 3 pT4. Six of 15 @entity1 (40%) presented with lymph node @entity3 and 5 (33%) had intraperitoneal @entity3 at cystectomy. These initial sites of metastatic spread included the prerectal space, @entity8376 , @entity5274 , and omentum and bowel serosa in 1 case each. Three @entity1 had subsequent @entity3 involving the prerectal space, @entity1744 in 1 each. Eight @entity1 had followup information available, including 3 who died of disease, 3 with disease and 2 with no evidence of disease. CONCLUSIONS: Of the @entity1 33% with the plasmacytoid variant of @entity189 presented with intraperitoneal disease spread and 20% had subsequent @entity3 involving serosal surfaces. The possibility of noncontiguous intraperitoneal spread involving serosal surfaces should be recognized to ensure proper intraoperative staging and clinical followup for @entity1 with @entity189 .
