Seborrheic Keratosis typically are rough
and have a ‘stuck on’ appearance
. Their colour may range from golden brown
to mid brown
to almost black
. They affect all skin types, but in dark skin they may also appear as multiple small dark brown or black bumps, especially on the face and the neck – in such cases this is called Dermatosis Papulosa Nigra.
Size varies from less than one centimetre to several centimetres in diameter.
Seborrheic Keratosis occur most often on the trunk, but they are also common on the head and neck. Some people may have just one lesion whilst others may have hundreds.
