A chance exists of recurrence after surgical removal of the cystic hygroma. The chance depends on the extent of the cystic hygroma and whether its wall was completely removed. [10]
Cystic lymphangioma that emerges during the first two trimesters of pregnancy is associated with genetic disorders such as Noonan syndrome and trisomies 13, 18, and 21. Chromosomal aneuploidy such as Turner syndrome or Down syndrome [8] were found in 40% of patients with cystic hygroma. [9]

Infantile hemangiomas are the most common type of vascular tumor to affect babies, [4] accounting for 90% of hemangiomas. [5] They are characterised by the abnormal proliferation of endothelial cells and of deviant blood vessel formation or architecture. [6]
