A normal 46,XX infant with a 46,XX/69,XXY placenta : a major contribution to the placenta is from a resorbed twin

A normal 46,XX infant with a 46,XX/69,XXY placenta : a major contribution to the placenta is from a resorbed twin

A predominantly triploid 69,XXY placenta was found associated with a normal 46,XX infant. Therefore, a triploid placenta is apparently capable of supporting normal fetal development. The chromosome and pathological results support the conclusion that the triploid placenta originates from a 'van...

Zusammenfassung:A predominantly triploid 69,XXY placenta was found associated with a normal 46,XX infant. Therefore, a triploid placenta is apparently capable of supporting normal fetal development. The chromosome and pathological results support the conclusion that the triploid placenta originates from a 'vanishing twin' pregnancy. This case is unusual in that persistence of the placenta from the vanished twin has virtually replaced most of the normal placenta.
