A 38-year-old woman had been suffering from exudation and pain from the hypogastrium several times a year from childhood. When she first presented to our hospital, a midline fistula of the abdominal skin was observed at 7 cm below the umbilicus. No infectious signs were revealed. Computed tomography revealed a cutaneous fistula extending toward the pubic bone and connected with the median umbilical ligament. Laparoscopic excision of the fistula was carried out in consideration of related residual disease. The median umbilical ligament diverged toward ventral skin and connected with the fistula. Histopathological examination in the lumen demonstrated that epithelium at the deep fistula was urothelial epithelium covered with the smooth muscle, and changed to stratified squamous epithelium around the opening of the fistula. Her postoperative course was uneventful and she has been free from recurrence as of one year after the operation.
