Seborrhoeic Keratoses, often called seborrhoeic warts, are very common, harmless, often pigmented growths on the skin. They appear almost as small, pigmented skin tags.
Seborrhoeic keratoses most often appear on the trunk, face and neck and are caused by a build-up of ordinary skin cells. They can become itchy and inflamed and can catch on clothing. While they are harmless, many people understandably do not like their appearance.
Typically, seborrhoeic keratoses have a rough surface ranging from light brown to dark brown to almost black. They can affect anyone and often become larger if left untreated. They can grow to a length of several centimetres across.
