Concomitant struma ovarii with serous cystadenoma in a background of tuberculosis: A rare and interesting presentation

Abstract

Struma ovarii is a rare ovarian tumour accounting for less than 5% of all ovarian neoplasms. It may occur with nongerminal epithelial ovarian neoplasms, but the coexistence of struma ovarii with serous cystadenoma is extremely uncommon with only 6 cases reported so far. Occurrence of these two in a setting of tubercular oophoritis is even rarer, and to the best of our knowledge, this is the first such case. We present a case of a 63-year-old multiparous postmenopausal woman who presented with an ovarian mass. Clinicoradiologically possibility of a neoplastic ovarian cyst was considered. Histopathological examination revealed coexisting triple pathologies; of which struma ovarii in a setting of tuberculosis was an incidental finding. This case is important, not only being rare, but it also highlights the importance of careful and extensive histopathological examination even in a seemingly simple cystic lesion of the ovary to avoid missing concomitant focal pathologies.
