Answer

In its pure form, mature cystic teratoma of the ovary is always benign, but in approximately 0.2-2% of cases, it may undergo malignant transformation into one of its elements, the majority of which are squamous cell carcinomas. The prognosis for patients with malignant degeneration is generally poor but dependent on stage and degenerated cell type. [4, 33]
