Should keratoacanthoma be treated surgically

: Keratoacanthoma is a rapidly growing cutaneous neoplasia of adult persons that may regress spontaneously. It is believed to arise from the hair follicles. It is sometimes difficult to distinguish keratoacantoma from squamous cell carcinoma either clinically or histologically. During ten years period (1992-2001) we were treating 18 patients with keratoacanthoma of the skin. We discuss here our experience with this tumor, and we conclude that early, complete excision is the treatment of choice for it.
