- description
- Treatment will consist of four weeks of daily application of 20% BA ointment to the dysplastic nevi, after which it will be removed surgically and examined. A similar dysplastic nevi will be removed as a control. Four groups of patients will be enrolled. The first group will apply the ointment once a day, the second twice a day, the third three times a day, and the fourth four times a day.

- description
- The development of any systemic toxicity (Grade 1 or greater) or Grade 3 local toxicity in 3 of 7 patients at any given dose level will result in the termination of all applications at that level; furthermore, no higher frequency of cohorts will be entered in the Study. This dose level is defined as a dose-limiting toxicity, with the maximum tolerated dose (MTD) being one dose level below.

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. * Patients with extensive chronic skin diseases such as extensive psoriasis, atopic dermatitis, or xeroderma pigmentosa will be excluded from the Study.
