Seborrheic keratosis are benign (harmless) in nature. However, as these lesions are rough and lie on the skin surface they can cause some irritation and discomfort. In some cases, they may begin to bleed as a result of the scaly skin on the top. Seborrheic keratosis sometimes can lead to aesthetic concern and therefore some people choose to have these removed. It is very rare for seborrheic keratosis to resolve themselves and so if they are causing concern having a consultation to discuss removal should be considered.
