D18: Haemangioma and lymphangioma, any site
Haemangioma and lymphangioma are groups of conditions that involve abnormal growth of blood vessels. Haemangiomas commonly appear at birth or in the first or second week of life. They look like a rubbery bump and are generally found on the face, scalp, chest or back. Despite their bright color, haemangiomas aren't usually painful or dangerous. They often grow rapidly during your child's first year, but they typically start to shrink when a child is about 1 year old.
Lymphangiomas, on the other hand, are rare, non-malignant masses that result from an error in the development of lymph sacs. These often enlarge slowly and painlessly and can affect any area of the body, although most commonly they affect the head and neck region. They seldom undergo spontaneous regression and can potentially create complications if they interfere with vital structures or become infected. Both conditions are not contagious and there is no known cause for them at this moment.
