Triploidy is a chromosomal abnormality caused by an additional set of haploid chromosomes. It is a common cause of early first-trimester miscarriages. Only very rarely are babies with triploidy born alive and even more rarely do they survive beyond the first few days of life. We present here a case of a term baby with confirmed paternal (diandric) triploidy and some unusual features, who survived for 50 days, and review the literature on those who survived.
