Struma ovarii, a rare ovarian neoplasm, is a monophyletic teratoma composed predominantly of thyroid tissue. It accounts for less than 5% of mature teratomas. Cystic struma ovarii is a rare variant wherein the thyroid component could be minimal in contrast to struma ovarii which has more than 50% 0f thyroid tissue. Diagnostic difficulties may arise if the Struma ovarii is either cystic or co-exists with any other cystic ovarian tumor. The dilemma gets worse when the tumor reveals only a few typical thyroid follicles and the gross examination shows a multi-loculated cyst with mucoid content. Extensive tissue sampling becomes mandatory in such cases to confirm cystic Struma ovarii and its co-existence with another cystic ovarian neoplasm.
We report one such rare occurrence of an ovarian tumor with co-existent cystic Struma ovarii and Mucinous cystadenoma. The case is reported for its rarity and for the diagnostic challenge encountered.
