A 49-year-old womam was admitted to our hospital with complaint of a mass in the external genitalia. The urethra was shifted left by a goose egg-sized tumor located close to it. The tumor was removed through the vaginal approach, which measured 5.0 × 4.0 × 3.2 cm weighted 32 grams. Histopathological findings demon-strated benign neurofibroma. To date, only 2 cases of paraurethral neurofibroma in woman were presented in the Japanese literature.
