Hyperkeratosis of the nipple and areola: report of 3 cases.
BACKGROUND
To date, approximately 43 cases of hyperkeratosis of the nipple and areola have been reported, most of which have been sporadic.


METHODS
We describe 3 patients with this dermatosis who were encountered in the outpatient clinic of the Department of Dermatology at the American University of Beirut Medical Center, Beirut, Lebanon, within a 1-year period.


CONCLUSIONS
Hyperkeratosis of the nipple and/or areola may be more common than what has been reported in the literature. We propose a revised classification for the condition.
