The Canal of Nuck
, described by Anton Nuck in 1691, is an abnormal patent pouch of peritoneum
extending into the labium majus
of women. It is analogous to the processus vaginalis
in males (see hydrocele
The pouch accompanies the gubernaculum during development of the urinary and reproductive organs, more specifically during the descent of the ovaries, and normally obliterates.
In rare cases, it may give rise to a cyst
, a hydrocele
in women, etc.
