title: Topical chemotherapy of dysplastic melanocytic nevi with 5% fluorouracil.
abstract: A therapeutic response to topical fluorouracil in a patient with the large atypical nevus syndrome is presented. Six of the patients' dysplastic melanocytic nevi were treated with topical fluorouracil. Four common acquired melanocytic nevi from normal individuals were also treated. All six dysplastic nevi responded with inflammation, ulceration, and subsequent disappearance of the lesion, while the four control melanocytic nevi remained unchanged. Although we do not presently advocate the therapeutic use of fluorouracil for large atypical nevi until its safety and efficacy have been established, the response reported herein may herald an important advance in the therapy of these troublesome lesions that are known to be histogenetic precursors of malignant melanoma.
