Seborrheic keratosis(SK) or Senile keratosis is one of the most common skin lesions in older adults. These lesions are not cancerous or malignant. They normally are black or brown in color and raised from skin surface with the appearance of a waxy or wart-like growth. The first stage in removal of these lesions is to distinguish them from cancerous lesions by dermoscopy. SK does not necessarily needs treatment but for cosmetic reasons or if they are irritated and constantly bleeding, they can be removed by different methods as the following:
• Freezing with liquid nitrogen or cryosurgery
• Scraping the skin's surface with curettage
• Burning with an electrocautery device
• Vaporizing them with an ablative laser
