Immature teratoma arising from uterine corpus in an 11‐year‐old girl: Case report and review of the literature

AbstractTeratomas are one of the most common germ cell tumors, and they usually occur in ovaries. Extragonadal teratomas are rare, especially immature ones. Only several cases of primary teratomas of the uterus have been reported since 1929. Here, the case of an 11‐year‐old patient who had a 6‐month history of sustained abnormal vaginal discharge is presented. Transabdominal ultrasonography revealed a solid mass in her uterus, resulting in the patient undergoing surgery. Examination of PET‐CT scans revealed a mass in the right ovary of the patient 20 days after surgery. The patient underwent a second surgery followed by chemotherapy. This is the youngest case among reported patients of primary immature uterine teratoma, and this patient showed no evidence of recurrence during 2 years of follow‐up.
