Abstract

Urinary bladder neoplasm is the 10th most common cancer in the world, predominantly affecting males. Nowadays incidence of urinary bladder carcinoma in female has increased. It is a uncommon type carcinoma of urinary bladder. It resembles to non-keratinizing carcinoma of nasopharynx. This study report a case of 65 years old male presented with painless gross hematuria for 3 weeks. Patient was a known case of Meckel's diverticulum. Ultrasonography and cystoscopy showed a mass on lateral wall of urinary bladder measuring 3x3 cm . A radical cystectomy of the urinary bladder tumor was done. He was diagnosed as case of lymphoepithelioma like carcinoma of urinary bladder along with benign prostate hyperplasia and Meckel's diverticulum was made with stage 2.According to the WHO classification criteria, Lymphoepithelioma like carcinoma is a subtype of undifferentiated carcinomas. Immunohistochemical stains are helpful to differentiate Lymphoepithelioma from primary lymphoma of the bladder. Differentiation of LELCB from urothelial carcinoma is important, since it has better prognosis compared to pure urothelial carcinoma. It is important to diagnose this neoplasm for therapeutic as well as prognostic purpose.
