[1][2] Hyperkeratosis is a condition in which there is a development of a warty thickening and pigmentation of the nipple, areola or both.

Since the skin lesions are mostly asymptomatic which do not require urgent medical attention most of the times, the reported cases may be underestimated than the actual prevalence.

In women, it usually occurs after puberty, aggravates during pregnancy and subsides after delivery.

Although, it is a benign condition, it is associated with cosmetic concerns and may also cause problems during breastfeeding.

The treatment consists of surgical methods or topical medications.
