[fō′kəmē′lyə]
Etymology: Gk, phoke, seal, melos, limb
a developmental anomaly characterized by absence of the upper part of one or more of the limbs so that the feet or hands or both are attached to the trunk of the body by short, irregularly shaped stumps, resembling the fins of a seal. The condition, caused by interference with the embryonic development of the long bones, is rare and is seen primarily as a side effect of the drug thalidomide taken during early pregnancy. Also called seal limbs. Compare amelia. phocomelic, adj.

phocomelia

A major, congenital limb defect featuring absence of all long bones so that the hands or feet are attached directly to the trunk and resemble flippers. Spontaneous cases of phocomelia are rare but the condition occurred in many children whose mothers were given thalidomide early in their pregnancy.

phocomelia

markedly defective development of either/both arms and legs, with hands and/or feet attached to the trunk; noted in 1960s (due to maternal medication with thalidomide early in pregnancy), and again in the 2000s (in some Third-World countries where mothers, who are unaware of their pregnancy take thalidomide to reduce progress of Hansen's disease)

phocomelia

congenital absence of the proximal portion of a limb or limbs, the distal parts being attached to the trunk by a small, irregularly shaped bone.
