title: [Plasmacytoid variant of urothelial carcinoma of urinary bladder: a case report].
abstract: We reported the experience with a case of plasmacytoid variant of urothelial carcinoma of urinary bladder. A 75-year-old woman complained of gross hematuria. She was hospitalized to be diagnosed as the bladder tumor on abdominal CT. TUR-BT was performed and pathological finding was invasive urothelial carcinoma. But she refused radical cystectomy. 2 months later, she was hospitalized again with worsening hematuria. Simple cystectomy was performed. Histological examination revealed a plasmacytoid appearance of the infiltrating tumor cells. Immunohistochemical stains for lymphoid markers were negative. Those findings lead to the diagnosis of plasmacytoid variant of urothelial carcinoma. She died due to local recurrence for 1.5 months after simple cystectomy.
