Picture of Vascular Malformations on Hand
Vascular malformations are a type of congenital defect that are comprised of irregular groupings of vessels like capillaries, veins, arteries, or lymphatic channels. These lesions are often made up of several different kinds of tissues. Port-wine stains (capillary malformation), venous malformations, and cystic hygroma (lymphatic malformation) are a few types of vascular malformations. Babies are born with these lesions, and they grow as the child grows. The photo depicts a venous malformation on the hand.
