Mohs' chemosurgery and skin cancer.

Experience in treating 1, 275 skin cancers with Mohs' chemosurgery is presented. The Mohs technic uses microscopic examination to avoid excision of normal tissue and assure complete removal of the tumor. Chemosurgery is indicated for tumors which are poorly demarcated or which arise in areas known to have a high recurrence rate. It is the procedure of choice for almost all recurrent lesions.
