To the Editor.— The report of F. E. Mohs, MD ( 212 :1956, 1970), entitled "Seborrheic Keratoses: Scarless Removal by Curettage and Oxidized Cellulose" is deserving of some comment. Dr. Mohs has made other very valuable original contributions to medicine, but curettage removal is probably preferred by the majority of the breed of dermatologists. Only for lesions larger than 2 to 3 cm in diameter might other procedures be chosen. In the first place, it is misleading to imply that the use of "oxidized cellulose" is the reason that the curettage procedure is not followed by scarring. The benign seborrheic keratosis is so superficial that it will heal without scar following proper curettage and the simplest of followup therapy, eg, a light covering for only a day or so until normal crust is established, and the use of simple 70% isopropyl alcohol to the individual crust once or twice a day.
