Initially lesions are usually light brown, small and flat or with a lightly rough texture They can become more raised and larger as the years go by. Their size varies from less than one centimetre to several centimetres across. They are usually skin coloured, tan or brown but may be black, white, pink or even grey. They give the impression that they are stuck onto the surface of the skin, especially when they are looked at from the side. The temptation is to peel them off (but this can not be done as they are a part of the skin). Some lesions may resemble small pigmented skin tags especially around the eyes and on the neck.
Seborrhoeic warts occur most often on the back, chest, face and neck but can occur anywhere on the body. Their numbers vary: one person may have just one seborrhoeic wart; others have hundreds of them. Once present, they usually stay, and new ones often appear with time.
