Abstract:
Hyperkeratosis of nipple and areola (HNA) is a rare benign condition of unknown etiology characterized by hyperkeratosis, verrucous thickening with brownish discoloration of nipple and areola. The nevoid form is predominantly seen in females and there are a few reports of HNA in men. Gynecomastia is benign enlargement of the male breast due to proliferation of the glandular component and associated with various conditions. It typically develops when there is an increase in the ratio of estrogen to androgen. We present a case of bilateral nevoid hyperkeratosis of nipple and areola occurring in a man with gynecomastia.
