Hyperkeratosis of the Nipples Developed during Pregnancy: report of a case / 대한피부과학회지

ABSTRACT

Hyperkeratosis of the nipple and areola is rare dermatosis that may be divided into three categories: a type of epidermal nevus, a type associated with ichthyosis and a type of nevoid form seen in voung women. A 23-year-old woman was seen for skin lesion involving both nipples. These changes were first noted when the patient was in the sixth month of gestation. Physical examinations revealed papillomatous thickening of both nipples with brownish black discoloration. Histopathological changes were mild hyperkeratosis, keratotic plugging and telangiectasia. It was interesting to note that the skin lesions disappeared spontaneously 7 days after parturition without treatment. A possible correlation between pregnancy and acquired form of this rare skin disorder is suggested.
