[Round ligament cyst, a rare condition simulating inguinal hernia. Case report].

Cysts of the inguinal cord are disorders that simulate inguinal hernias and manifest as inguinal masses and, in some cases, are accompanied by pain that can simulate a complicated inguinal hernia. We report the third case of a round ligament cyst in a 21-year-old female with a mass in the right inguinal area with intermittent pain. The patient was subjected to surgical exploration of the right inguinal area where a round ligament cyst was found.
