title: Primary malignant lymphoma of urinary bladder.
abstract: A case of primary malignant lymphoma of the urinary bladder is described. The classic presentation of gross hematuria and dysuria with a benign clinical course is illustrated. From a review of the literature and our experience, we conclude that localized primary lymphoma of the bladder, especially those with favorable histologic findings, often does not require medical or surgical intervention. Persistent irritative bladder symptoms can be palliated adequately with external beam radiotherapy, while surgical intervention is rarely indicated.
