ABSTRACT
A 38-year-old woman was referred for urethral tumor treatment. Needle biopsy of the tumor was performed. Histologically, the tumor was composed of large polygonal cells with eosinophilic and periodic acid-Schiff (PAS)-positive granular cytoplasm, indistinct cell margins and small round central nuclei. Immunohistochemical staining for S100 protein, vimentin, and neuron-specific enolase (NSE) was positive, indicating that it was a granular cell tumor. Excision of the tumor including the urethra and appendicovesicostomy using the Mitrofanoff principle were performed. There has been no tumor recurrence in the 8 months after the operation.

A 66-year-old man was admitted with distal edema of his right leg. He had undergone radical prostatectomy and pelvic lymphadenectomy for prostatic cancer 23 days previously. Abdominal computed tomography (CT) showed a lymphocyst (4.5 x 3.0 cm) along the right pelvic wall compressing the right external iliac vein. CT with contrast medium showed thrombus formation (about 9 cm) in the distal portion of the right external iliac vein and femoral vein. An inferior vena cava filter was placed to prevent pulmonary embolism, and anticoagulation with warfarin was started. One week later, CT showed shrinkage of the lymphocyst and thrombus in the vein, as well as a large thrombus trapped in the filter. Follow-up CT taken 2 months later revealed marked reduction of the lymphocyst and absence of thrombus in both the vein and filter. A lymphocyst, also known as a lymphocele, is a complication of radical pelvic surgery. Most lymphocysts are asymptomatic and regress spontaneously, but may lead to deep vein thrombosis and pulmonary embolism, usually a few weeks after surgery. Careful observation is needed even after discharge from hospital.

We successfully treated three patients using the flexible video cystoscope (CYF-240A, Olympus, Japan) for superficial bladder cancer under local anesthesia and/or spinal anesthesia. The major advantage of this new technique is that surgeons can use digital pictures and high frequency cauterization. This new system provides good quality of life for bladder cancer patients experiencing frequent recurrences.
