Primary lymphoma of the bladder treated successfully with mitozantrone gel.

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