A rare cause for hematuria: Lymphoma of the urinary bladder

Primary lymphomas of the urinary bladder are rare and majority present with hematuria. Patients are usually elderly females with a history of recurrent cystitis. The diagnosis is clinched after imaging and biopsy of suspicious lesions in the bladder. The prognosis is good irrespective of the modality of treatment. With this background, we report a case of primary marginal zone lymphoma of the urinary bladder (Stage IE) in a young lady with no history of cystitis, who presented with isolated hematuria. After treatment with radiotherapy alone, patient is in complete remission for the past 18 months. The timely diagnosis in a patient with hematuria holds the key to successful treatment and its importance cannot be overemphasized.
