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. date: 2011-04-15 date_type: published publication: Online Journal of Health and Allied Sciences volume: 10 number: 1 publisher: BS Kakkilaya refereed: TRUE referencetext: 1.
