Background: Lesions arising in the round ligament and canal of Nuck are uncommon and may prove challenging to clinicians. Objectives: To review the scope of lesions affecting the round ligament and canal of Nuck. Materials and Methods: A literature review was conducted. A Medline search was used, using the terms round ligament, canal of Nuck, and uterine neoplasms. Results: Reported lesions of the round ligament and canal of Nuck were reviewed. Many of these lesions can be mistaken for each other clinically. Conclusions: A review of the scope of rectovaginal lesions is presented to assist in developing a differential diagnosis if a patient with such a lesion is encountered. (J GYNECOL SURG 31:245)
