Treatment: Treatments can be divided into surgical and nonsurgical forms. The choice depends on various factors, most importantly the location and size of the lesion. Some tumors are best treated surgically, whereas others are best treated medically.
Simple excision or electrodessication and curettage are highly effective treatments. Cryotherapy is another destructive method that can be selectively used with good success. Medical therapies include the application of 5-fluorouracil, imiquimod, or 5-aminolevulinic acid followed by exposure to blue light. These all have been reported to be successful. The risk of recurrence is between 3% and 10% depending on the type of therapy used.
