Lymphangioma causes

Causes
There is no known cause for these vascular abnormalities. Genetic syndromes that are associated with cystic hygroma include Turner syndrome and some trisomies e.g. trisomy 13, trisomy 18 and trisomy 21.

The tumor is a hamartoma or vascular developmental anomaly arising from lymphatic vessels, manifesting as a raised, soft, shaggy, bubbly, pinkish-white lesion; cosmetic considerations may warrant attempted removal of lymphangiomas.
