Chorion angioma is a relatively rare disease, which was first described by J. Clarke in 1978. In 1934 Szathmary summarized 238 cases from literature. In Japan only 16 cases have been reported. Our case is as follows; A primigravida of 39 years of age. After a travelling by railway at the 9th month of pregnancy she noticed the absence of fetal movements with great distension of the abdomen ana dyspnea so that she was admitted to our clinic. Clinical diagnosis was acute hydramnion and the labor was induced by rupturing the bag of water. The amniotic fluid was over 3,600 cc. The child died 5 minutes after delivery. The placenta weighed 1090 g, and on the maternal surface a fist-sized, dark red violet tumor was noted. Biopsy revealed chorion angioma. Undoubtedly it was the rapid growth of this tumor which caused acute hydramnion. The cause of the disease is not clear. Wassermann's reaction of the patient, the husband and the child were all negative, while Rh factor were all positive.
