title: Villar’s Nodule creator: Sengupta, M creator: Naskar, A creator: Gon, S creator: Majumdar, B subject: Online Journal of Health and Allied Sciences description: Villar’s Nodule or primary umbilical endometrioma is a rare condition, with an estimated incidence of 0.5 to 1% of all patients with endometrial ectopia. Several aetiological theories have been proposed for its pathogenesis with coelomic metaplasia being the favoured one and also, umbilicus may acts as a physiological scar with a predilection for endometrial tissue in the development of spontaneous umbilical endometriosis. Since endometriosis remains a diagnostic and therapeutic enigma even today, largely due to its variable presentations, we, hereby report a case of primary umbilical endometrioma due to its rarity and unusual presentation. publisher: BS Kakkilaya contributor: Kakkilaya, Dr Srinivas date: 2011-04-15 type: Journal (On-line/Unpaginated) type: PeerReviewed format: application/pdf identifier: http://cogprints.org/7832/1/2011-1-19.pdf identifier: Sengupta, M and Naskar, A and Gon, S and Majumdar, B (2011) Villar’s Nodule.
