Birthmark

Birthmark is defined as abnormal skin colouration since birth or a few weeks after birth. Most birthmarks are non-cancerous while some may pose health risks. Common birthmark pigmentations are pigmented birthmarks, macular stains, hemangiomas, and port wine stains.
 
Pigmented Birthmarks

• Nevus of Ota and Nevus of Hori - slate-brown or blue/grey coloured birthmarks found on the face.
• Mongolian spots - bruised or bluish birthmarks found on the back or buttocks of babies.
• Cafe-au-lait spots - light brown to dark flat spots associated with neurofibromatosis if there are 6 or more spots.
• Nevi or moles - flesh-coloured to light-to-dark brown and should be checked for changes using the ABCDE method.

• Macular stains - mild red marks that usually appear on the forehead and eyelids or the back of the neck.
• Hemangiomas - growths made up of many tiny blood vessels, commonly found on the face, trunks, arms, and legs.
• Port wine stains - flat pink, red, or purple marks caused by abnormal development of capillaries, commonly found on the face, trunk, arms, or legs.
