Polymelia is a type of rare birth disorder which involved in forming and developing extra parts of the body that usually impact on deformed and shrunken limbs. Polymelia causes body to develop extra limbs that are commonly deformed came from supposedly twins which happens when Embryo starts as conjoined twins.

Why Polymelia Occurs? Polymelia Causes in Humans

There are two hypotheses as to why polymelia occurs. Sometimes an embryo started as conjoined twins. It occurs when a twin embryo begins developing in utero, but the pair does not fully separate. One twin degenerated completely except for one or more limbs, which end up attached to the other twin. Or, in other cases, extra number of limb buds start developing due to an anomaly and give rise to additional limbs,” Dr Singh said.  Most commonly these limbs don’t develop as much as the others hands or legs.

Polymelia occurs in the womb when the cells form abnormally during embryonic development or sometimes an embryo started as conjoined twins. Their are several reasons of polymelia, a rare genetic disorder, including the incorrect splitting of limbs or the re-absorbance of a conjoined twin back into the body. These anomalies are usually associated with genetic factors including chromosomes, tamogenes, and environmental agents.

Humans are not the only one being subjected to such a rare disease but animals (most species of land dwelling animals) also been a target to such abnormal growths. There are very few documented cases of Polymelia around the world. According to worldwide reports of the census of Polymelia records, there have been 14 recorded cases in humans and 21 recorded cases among animals since 2005. There are several, quite recent, examples of mothers giving birth to children with extra limbs. We report rarest cases of this rare birth disorder, cases of polymelia.
