Dermabrasion for showers of seborrheic keratoses.

Seborrheic keratoses, skin tumors of undetermined etiology, are easily traumatized with consequent local irritation and inflammation, and are cosmetically undesirable. They can occasionally undergo malignant degeneration. A rapid increase in size and number of these lesions is thought by many to be a sign of internal malignancy. Dermabrasion using a diamond fraise is a simple and fast method for removing multiple seborrheic keratoses with minimal trauma, rapid healing, and good cosmetic results.
