Moles, or pigmented nevi, are growths that are flesh-coloured, brown or black, appearing anywhere on the skin alone or in groups. They may be irregular in shape and flat, or raised and lumpy.
This occurs when many new blood vessels grow in a specific area on the skin, causing lesions to develop within a few weeks after birth. It is a harmless tumour that is the most common in infancy.
These range from pale pink to deep wine-red in colour. They appear irregular, large and are caused by dilated blood vessels. Over time, they may become thick, or develop small ridges or bumps. It occurs in 0.3% of the population.

Macular stains, or salmon patches, are small blood vessels that are visible through the skin. They are commonly on the forehead, eyelids, upper lip, between the eyebrows and back of neck. Often, they fade as the infant grows.
These spots are light tan or brown, usually oval in shape – usually appearing at birth or early
childhood.
They resemble bruises, often seen on the buttocks, lower back, flanks and shoulders, with wavy borders and irregular shape. The blue colour is caused by melanocytes deep under the skin.
