Seborrheic keratosis are common, harmless lesions that can appear during adult life as a part of the aging process and can often be referred to as senile or brown warts.
Initially they develop as light brown, slightly raised spots, however, over time will darken in colour and gradually increase in thickness, leaving them with a rough surface. Seborrheic keratosis can appear as an individual lesion or as multiple lesions, affecting both sun exposed and non-sun exposed regions of the body.
Treatment through the use of either diathermy or laser treatment can provide effective results for patients with less risk of scarring than liquid nitrogen (dry ice) treatment or shaving off. A topical anaesthetic cream is used with diathermy treatment, whereas laser cooling is usually sufficient to keep the treatment comfortable during laser treatment.
Immediately post treatment the lesion appears discoloured either darker, grey or whitened with the surrounding area appearing inflamed. A soothing ointment is applied post treatment, then the lesion is left to fall off over the following days.
