Soft tissue metastasis of an immature teratoma of the ovary

In patients with immature teratoma of the ovary, blood-borne metastasis to organ parenchyma, such as the lungs, liver, or brain, are uncommon. Moreover, soft tissue metastasis is extremely rare. We describe a 31-year-old woman with an immature teratoma of the left ovary, which metastasized to soft tissue of the right thigh after surgery. Because of the rarity of this condition, we report the results of treatment and review the literature.
