A Seborrhoeic Wart is also known as Seborrhoeic Keratosis. In the past they were also called “senile” warts. They usually look like greasy or crusty spots which seem stuck on to the skin. The colour varies greatly, depending on the underlying skin colour and its melanin content. Usually they are darkish brown or black.
Seborrhoeic warts are usually round or oval, but can also have an irregular shape. Their size can vary from around a few millimeters to large areas of usually “confluent” warts of larger sizes.
Seborrhoeic warts tend to appear from the early to mid-forties onwards. They can sometimes run in families. We do not know the cause of seborrhoeic warts. Some patients develop several and sometimes many of these keratotic lesions as they become older. Also, as time goes by, each wart tends to grow slightly and become darker. Sometimes they can fall off by themselves, particularly if they are quite brittle while the fatty ones do not tend to fall of easily. Sometimes a wart can get a bit
inflamed and can fall off afterwards. They can occur anywhere on your body, other than on your palms or soles.
