"7832","Villar’s Nodule","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.","http://cogprints.org/7832/","Sengupta, M and Naskar, A and Gon, S and Majumdar, B","Kakkilaya, Dr Srinivas"," Sengupta, M and Naskar, A and Gon, S and Majumdar, B (2011) Villar’s Nodule.
