Urachal carcinoma during pregnancy.

We report a case of Stage T4aN2M0 urachal carcinoma that was diagnosed early in pregnancy. Because positive pelvic lymph nodes and uterine involvement were present, surgical resection, including hysterectomy with termination of the pregnancy, and postoperative radiotherapy were performed. The treatment options, which largely depend on the duration of the pregnancy, the tumor stage, and the patient's desire to continue the pregnancy, are discussed.
