Case History

This boy was first referred to genetics at 13 months old due to suspected vascular malformation of the left lower limb. He is twin 1 of a twin pregnancy with birth weight 3.23kg. At birth, he was noted to have non-elevated erythematous lesion over the lateral thigh and knee with no limb asymmetry. Subsequently, there was swelling of the left lower limb since 2-3 months old. Ultrasound finding is compatible with lymphangioma.

He was born from a non-consanguineous Chinese family with negative family history.
