Abstract
Hydrocele in the Canal of Nuck is a condition of female fetal development. The Canal of Nuck is a patent tubular peritoneal fold that travels with the round ligament to its attachment on the labia major. Failure of complete obliteration of the Canal of Nuck during fetal development predisposes females to development of a hydrocele or an inguinal hernia during post-pubertal or adult stages. We present a case of a 21 year old female with a tender reducible labial mass diagnosed as a Hydrocele in the Canal of Nuck.
