Primary lymphoma of the bladder treated successfully with mitozantrone gel

We describe a young man who presented with a short history of painless haem aturia. Subsequent investigations and biopsy of lesions found in his bladde r at cystoscopy confirmed the diagnosis of primary lymphoma of the bladder. Computed tomography studies confirmed the disease was localised to his bla dder. Unfortunately, the tumour was not eradicated by radiotherapy. However , it was successfully treated with intravesical mitozantrone given in a nov el gel formation. Three years after diagnosis the patient remains well with no evidence of recurrence.
