Abstract
A 23-year-old woman developed right inguinal pain and abdominal distention. She had a bulging mass and tenderness due to abdominal distention in the right inguinal region. Pelvic CT scan showed a cystic mass in the right inguinal region. Surgery was performed with a diagnosis of a cystic mass associated with a right inguinal hernia. Intraoperative findings showed that the cyst contained a dark red liquid and that the hernial sac was connected to the cyst. A high ligation of the hernial sac was done, the cyst was extracted and the internal hernial ring was closed using Marcy's method. On pathohistology, the cysts inner cavity was covered with mesothelial cells, as part of the vaginal process of the peritoneum, and the findings of endometriosis were noted.
The vaginal process of the peritoneum that remains open in women is called Nuck's canal. A hydrocele of Nuck's canal is a cyst that stores liquid in Nuck's canal. In endometriosis, endometrial cells are present in regions other than the intrauterine cavity. Endometriosis located in Nuck's canal is rare. Therefore, we report this adult case of endometriosis located in a hydrocele of Nuck's canal.
