Inclusion Criteria: All races are eligible for entry into the Study. All patients must have been histologically documented (by a punch biopsy) for dysplastic nevi with moderate to severe dysplasia (DMN). A similar biopsy proven DMN that will serve as the control needs to be available. Patients must be healthy and active in normal pursuits of life and be able to provide informed written consent. Localized dermatological conditions like psoriasis or actinic keratosis will not be an exclusion criteria. Patients must be ambulatory with an ECOG status < 2; they will not be hospitalized as part of the Study. All patients in this study will have, in addition to a normal clinical examination, a thorough skin examination. Whenever possible, periodic photographs of their lesions will be taken. Additional tests for all patients within 30 days of the initiation of topical application include urinalysis, a liver function test (LFT), and blood tests for complete blood count (CBC), BUN, and creatinine. Exclusion Criteria: Women who are pregnant and/or nursing will be excluded. A pregnancy test will be performed on each pre-menopausal woman within two days of entry into the Study, and a negative pregnancy test must be recorded on the case report form prior to initiating use of the topical application. Patients who are being treated for other chronic debilitating diseases (cardiac, pulmonary, or any other organ specific diseases). Immuno-suppressed patients, either due to chemotherapy and radiation therapy or known immunodeficiency diseases (e.g., AIDS). Patients with other active malignancies within the past five years, excluding noninvasive skin or cervical carcinoma. Patients with any other serious medical or psychiatric illness that would prevent informed consent.
