Ulcerative lichen planus. Follow-up of surgical excision and grafting.

Four patients with ulcerative lichen planus of the feet underwent total excision and split-thickness skin grafting of the affected areas. One patient underwent grafting in 1951, and remained free of recurrent ulcers for 26 years. Another, who had an 18-year follow-up after grafting, required an additional procedure. The possibility of squamous cell carcinoma in ulcerative lichen planus is considerable, lending further support to the concept that excision with grafting is the treatment of choice for these lesions.
