Peripheral T-Cell Lymphoma of Urinary Bladder Presenting With Just Irritative Voiding Symptoms

Peripheral T-cell lymphoma (PTCL) of the urinary bladder is rare. PTCL can either be primary or secondary and is difficult to differentiate from other inflammatory bladder lesions. We report a case of PTCL involving the bladder in a 63-year-old man who complained of dysuria without gross hematuria. In this report, we focus on the cystoscopic and histologic findings of urinary bladder lymphoma and its differential diagnosis.
