甚한 小腸出血을 同伴한 子宮外 惡性脈絡膜上皮腫 : 症 例 報 告 Report of a Case without Demonstrable Primary Trophoblastic Malignancy in the Uterus = Ectopic Choriocarcinoma with Massive Hemorrhage in the Small Intestine

다국어 초록 (Multilingual Abstract)

The majority of choriocarcinomas are known to arise from the embryonic chorion. Choriocarcinoma may follow or coexist with a hydatidiform mole, normal or abnormal pregnancy, or abortion. The primary lesion is, therefore, usually harbored in the uterus. Teratomatous choriocarcinoma, on the other hand, is generally located in the gonads or, rarely, in other sites of the body.
Since primary location of the nonteratomatous choriocarcinoma is usually in the genital organs, when the lesion in found at other sites it is considered to be an ectopic lesion.
Several reports of ectopic choriocarcinomas without evidence of trophophoblastic tumors in genital organs have appeared in the literature.
The purpose of this paper is to report a case with ectopic choriocarcinoma in the small intestine. The patient had complained massive intestinal hemorrhage. The primary trophoblastic tumors were not found in the uterus.
