Histopathological spectrum of laparoscopicaly treated endometriotic ovarian cysts

Introduction: Endometriosis is defined as presence of endometrial glands and stroma outside the uterine cavity. This definition suggests that confirming the endometrial stroma and glands in ectopic location histopathologically should be necessary for diagnosis of endometriosis. But in some cases, one or both of these components may be absent or obscured by a superimposed hemorrhagic, inflammatory or fibrotic process and all that remains is a fibrotic area containing haemosiderin macrophages. In such cases only a presumptive diagnosis of endometriosis may be made with the possibility of other hemorrhagic ovarian cysts to be kept in mind. Materials and Methods: We have studied histopathological reports of laparoscopically treated endometriotic ovarian cysts retrospectively from january 2014 to july 2016 in PSRI hospital and interpreted the results Results: Out of total 52 endometriotic ovarian cystectomies done, only 27(51.92%) were reported as confirmed diagnosis of endometriotic ovarian cyst. Seven (13.46%) were reported as hemorrhagic corpus luteal cyst, 5 (9.61%) as hemorrhagic follicular cyst, 3(5.76%) were reported as theca lutien cyst, 5(9.61%) as benign hemorrhagic ovarian cyst most likely consistent with endometriotic etiology, 4 (7.69%) as benign hemorrhagic cysts of indeterminate nature and one (1.92%) as non mucinous cystadenoma of ovary. None was reported to be malignant or borderline. Conclusion: Through this study we would like to emphasise the various possible histopathological outcomes of an apparant endometriotic cyst which would change the further plan of management of patient.
