title: Concurrent bladder lymphoma and bladder cancer presenting as metastatic bladder cancer.
abstract: Malignant lymphoma of the bladder is a rare lesion, representing approximately 0.2% of the primary lesions and approximately 1.8% of the secondary lesions. A disseminated lymphoma presenting as a bladder mass is an infrequent phenomenon. The authors report the case of a 71-year-old patient with concurrent bladder lymphoma and bladder cancer presenting as metastatic bladder cancer. To the best of our knowledge, this is the first report of concurrent bladder lymphoma and bladder cancer.
