A vascular malformation of developmental origin characterized pathologically by ectasia of superficial dermal capillaries, and clinically by persistent macular erythema. In the past, port wine stains have frequently been termed capillary hemangiomas, which they are not; unfortunately this confusing practice persists: HEMANGIOMA, CAPILLARY is neoplastic, a port-wine stain is non-neoplastic. Port-wine stains vary in color from fairly pale pink to deep red or purple and in size from a few millimeters to many centimeters in diameter. The face is the most frequently affected site and they are most often unilateral. (From Rook et al., Textbook of Dermatology, 5th ed, p483)
a congenital overabundance of blood vessels beneath the surface of the skin
a flat birthmark varying from pink to purple
a flat hemangioma made of dilated blood capillaries
an area of skin that is either maroon (a purplish-red color) or dark red
an area of skin that is level with the outer layer of skin and is maroon or dark red in colour
a vascular (containing vessels) birthmark made of enlarged capillaries in the skin, which produce a reddish-purplish discoloration of the skin
a vascular malformation of capillary blood vessels in the deeper layers of the skin
a flat, reddish-purple mark that appears most often on the face and on the back of the neck. A type of birthmark. Also called nevus flammeus.
Port-wine stains (PWS) are the most common kind of abnormality of blood vessel development and involves dilated capillaries in the skin. PWS may occur anywhere on the body; however, the risk of brain or eye involvement is very low if the PWS is located anywhere other than the upper face.
a flat pink, red, or purplish lesion, present at birth; a capillary malformation
A type of hemangioma characterized by a mark on the skin that resembles the rich red color of port wine. Port-wine stains are caused by an abnormal concentration of capillaries. This type of birthmark is also referred to as nevus flammeus.
a flat, pink, red, or purple colored birthmark.
A port-wine stain or naevus flammeus is a vascular birthmark consisting of superficial and deep dilated capillaries in the skin which produce a reddish to purplish discoloration of the skin. They are so called for their colour, resembling that of Port wine. It is part of the family of disorders known as vascular malformations.
