Para-Adnexal Cysts- A Clinicopathological Study

Abstract

Introduction: Para-adnexal cysts (paraovarian and paratubal) constitutes a homogenous group of cystic lesions originating from mesosalphinx or broad ligament, located in proximity of the fallopian tube and ovary. As with the lesions of the adnexa, paraovarian and paratubal cysts can be neoplastic but are often misinterpreted as true functional cysts. A correct radiological and clinical diagnosis would be useful in order to render necessary treatment. Aim: To highlight the histomorphologic spectrum of the para-adnexal cysts and correlate with clinical findings. Materials and Methods: The present study was a retrospective study conducted in the Department of Pathology, Rajarajeswari Medical College, Bengaluru, Karnataka, India, from January 2017 to June 2019. All specimens including salpingo-ophorectomy specimens which harboured paratubal or paraovarain cysts, or paratubal/paraovarian cysts diagnosed on radiology and resected and sent separately for histopathologic evaluation were sampled and included in the study. All surgically and radiologically proven paratubal and paraovarian cystic lesions were included and solid lesions were excluded. The results were analysed using descriptive statistics. Results: Present study analysed 114 cases and found that 28 of the cases showed neoplastic cysts, one of them showing a serous borderline tumour, which have the potential to turn malignant. The mean age of diagnosis was 40.1 years and menstrual abnormalities was the most common presentation. Of the neoplastic cysts, paraovarian cysts (78.6%) were more common than paratubal cysts (21.4%). About 75.4 % were non neoplastic cysts and 24.6% were neoplastic. Conclusion: Para-adnexal cysts are often misdiagnosed or not sampled as they are thought of as functional cysts. Histopathologic evaluation of these lesions would help in understanding the different histological types that would arise in para-adnexal sites which in turn helps in better management of these patients.
