Primary @entity1893 rarely arise from the lower urinary tract, the urethra being the most uncommon site of origin. Herein, we report the immunohistochemical findings of a case of primary marginal zone @entity1892 ( @entity1074 ) arising from the male urethra. To clarify the clinicopathological findings of primary @entity706 , we reviewed 14 previously reported cases. A 56-year-old @entity1 presented with gross @entity811 . Cystourethroscopy demonstrated a nodular bulge of the urethral wall. Histologically, a transurethral biopsy specimen showed a dense lymphoplasmacytoid infiltrate in the urethral mucosa. The @entity5 cells were composed of centrocyte-like cells, plasma cells and plasmacytoid cells. A few plasma cells contained intracytoplasmic pseudoinclusions (Dutcher bodies). Immunohistochemical study revealed monotypic intracytoplasmic kappa-light chain in the plasma cells and plasmacytoid cells. The @entity1 received a total of 50 Gy extrabeam irradiation. Follow-up 21 months later did not disclose any sign of local or other recurrences.
