Nevoid hyperkeratosis of the nipple and areola: treatment with topical retinoic acid.
Nevoid hyperkeratosis of the nipple and areola is a rare dermatosis with unknown etiology, (Perez-Izquierdo JM, Vilata JJ, Sanchez JL, et al. Retinoic acid treatment of nipple hyperkeratosis. Arch Dermatol 1990;126:687-688). Only 40 cases have been reported until 1997 (Alpsoy E, Yilmaz E, Aykol A. Hyperkeratosis of the nipple: report of two cases. J Dermatol 1997;24:43-45). The disease has a benign course and may only be a cosmetic problem. Different modalities have been used in the treatment of NHNA. In our case treatment with topical retinoic acid induced an acceptable response.
