Core Tip

Core Tip: Malignant struma ovarii (MSO) with biologically malignant behavior is an extremely rare disease. The rarity of MSO and the nonspecific clinical presentation make it very difficult to diagnose preoperatively. We report a case of MSO, for which we analyzed a combination of pathological and immunohistochemical findings, to improve the understanding of this disease. A clear preoperative diagnosis of MSO can be particularly helpful for doctors in formulating the best treatment plan, allowing patients to avoid unnecessary treatments to the greatest extent possible.
