[Multiple clear-cell acanthoma]

Abstract

Clear cell acanthoma is a benign tumor reported by Degos et al. in 1962. Most commonly the acanthoma presents as a solitary nodule on the lower limb in late middle-aged persons. We've found only 11 papers about multiple clear cell acanthoma. We describe a 73 years old patient who had 21 lesions, the highest number found in the literature.
