As increased middle cerebral artery peak systolic velocity, the fetal hydrops was caused by a placental tumor such as a chorioangioma; however, the tumor was atypical. Fetal blood hemoglobin was 8.3 g\/dl on percutaneous umbilical cord blood sampling. After erythrocytes transfusion to the fetus, the mother normally delivered at 38\u2009weeks' gestation. The placental tumor was histologically diagnosed as a necrotic chorioangioma. Obstetricians should note such atypical chorioangiomas when differential diagnosis of placental tumors.<\/jats:p>","DOI":"10.1111\/jog.14685","type":"journal-article","created":{"date-parts":[[2021,2,1]],"date-time":"2021-02-01T04:37:02Z","timestamp":1612154222000},"page":"1191-1194","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Degenerative type of placental chorioangioma requiring fetal blood transfusion"],"prefix":"10.1111","volume":"47","author":[{"given":"Hideyuki","family":"Iwahata","sequence":"first","affiliation":[{"name":"Department Obstetrics and Gynecology St. Marianna University School of Medicine  Kawasaki Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuriko","family":"Iwahata","sequence":"additional","affiliation":[{"name":"Department Obstetrics and Gynecology St. Marianna University School of Medicine  Kawasaki Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chika","family":"Homma","sequence":"additional","affiliation":[{"name":"Department Obstetrics and Gynecology St. Marianna University School of Medicine  Kawasaki Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akiko","family":"Kurasaki","sequence":"additional","affiliation":[{"name":"Department Obstetrics and Gynecology St. Marianna University School of Medicine  Kawasaki Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junichi","family":"Hasegawa","sequence":"additional","affiliation":[{"name":"Department Obstetrics and Gynecology St. Marianna University School of Medicine  Kawasaki Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nao","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department Obstetrics and Gynecology St. Marianna University School of Medicine  Kawasaki Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,1,31]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.placenta.2010.10.013"},{"key":"e_1_2_5_3_1","first-page":"926743","article-title":"Prenatal diagnosis and fetomaternal outcomes of two cases with placental chorioangioma","volume":"2013","author":"Artunc Ulkumen B","year":"2013","journal-title":"Case Rep Obstet Gynecol"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2018-227828"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200001063420102"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/1066896915585347"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1148\/rg.274065207"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.7451"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.2000.00127.x"},{"key":"e_1_2_5_10_1","first-page":"1028","article-title":"Perinatal outcome after prenatal diagnosis of placental chorioangioma*1","volume":"102","author":"Sepulveda W","year":"2003","journal-title":"Obstetrics & Gynecology"}],"container-title":["Journal of Obstetrics and Gynaecology Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jog.14685","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/jog.14685","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/jog.14685","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,2]],"date-time":"2023-09-02T08:37:46Z","timestamp":1693643866000},"score":1,"resource":{"primary":{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/10.1111\/jog.14685"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,1,31]]},"references-count":9,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2021,3]]}},"alternative-id":["10.1111\/jog.14685"],"URL":"https:\/\/doi.org\/10.1111\/jog.14685","archive":["Portico"],"relation":{},"ISSN":["1341-8076","1447-0756"],"issn-type":[{"value":"1341-8076","type":"print"},{"value":"1447-0756","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,1,31]]},"assertion":[{"value":"2020-11-19","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-01-16","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-01-31","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
