Estrogen-induced hyperkeratosis of the nipple.
Mold DE, Jegasothy BV.
Cutis 1980 Jul;26(1):95-6 Abstract quote
Hyperkeratosis of the nipple and areola has been classically divided into three categories: a part of an epidermal nevus, a type associated with ichthyosis, and a nevoid form seen in young women.
A case of hyperkeratosis of the nipples in a patient with adenocarcinoma of the prostate treated with diethylstilbestrol is described herein. A possible correlation between estrogens and an acquired form of this rare skin disorder is suggested.
Hyperkeratosis of nipple and areola.
Mehregan AH, Rahbari H.
Arch Dermatol 1977 Dec;113(12):1691-2 Abstract quote
Hyperkeratosis of the nipple and areola is a rare condition that may occur in association with various forms of ichthyosis or as the result of extension of an epidermal nevus. The nevoid form is extremely rare and appears most commonly in women in their second or third decade of life. It is characterized by verrucous thickening and brownish discoloration of both nipples and areolae. Thirteen cases of this type have been reported.
We are describing two additional cases to bring the total to 15 instances.

J Am Acad Dermatol 1985 Oct;13(4):596-8 Abstract quote
Hyperkeratosis of the nipple and areola is a rare condition. We report two cases of hyperkeratosis of the nipple and areola occurring in men with no underlying endocrinopathy or synthetic estrogenic drug therapy. Both patients demonstrated prompt resolution of the hyperkeratosis of the nipples with a keratolytic gel.
Because our cases were not associated with ichthyosis or epidermal nevus, they best fit into the category of nevoid hyperkeratosis of the nipples.

Hyperkeratosis of the nipple and areola is a rare condition; its characteristic properties are verrucous thickening and brownish discoloration of the nipples and areola. The nevoid form of the disease is extremely rare, usually seen in women in the second or third decade of life. The nipple is seldom affected alone.
We report two cases of the nevoid form of hyperkeratosis of the nipple. In both female patients, lesions developed after puberty and were confined to both nipples alone. One of the patients' lesions became darker and more verrucous during pregnancy, making breast feeding impossible.

Although nevoid hyperkeratosis of the nipple and areola was initially described in 1923, there are only case reports or reviews about it; no large series have been documented to date.
The clinical features of the reported cases in the literature are not uniform, and it is questioned whether nevoid hyperkeratosis of the nipple and areola is a distinct clinicopathologic entity or a clinical presentation of various dermatoses. We describe 7 cases with hyperkeratotic nevoid lesions localized on the nipple and areola with different clinical features. None of them had any other associated dermatologic or systemic disease. Histopathologic examination was performed in 6 patients. Four of them had common histopathologic features suggesting a distinct entity, namely, nevoid hyperkeratosis of the nipple and areola; 2 of them had histopathologic features consistent with seborrheic keratosis.
Seborrheic keratosis presents as sharply demarcated papules or plaques, whereas nevoid hyperkeratosis of the nipple or areola presents as a plaque diffusely involving the nipple or the areola.

Cutis 1996 May;57(5):354-6 Abstract quote
Nevoid hyperkeratosis of the nipple and areola is a unique clinical entity and a diagnosis of exclusion. The patient presenting with nipple/areolar hyperkeratosis must be examined carefully for other underlying cutaneous diseases such as epidermal nevi, ichthyosis, acanthosis nigricans, Darier's disease, cutaneous T-cell lymphoma, and other chronic skin dermatitides that may be responsible for the changes. If no other clinical findings are evident, the diagnosis can be made. Although the disorder is more common in women of childbearing age, men may show nevoid changes after estrogen therapy or idiopathically.
The use of topical 12 percent lactic acid lotion (Lac-Hydrin) resolves the skin changes over a six-month period.

Eur J Dermatol 2002 Jan-Feb;12(1):79-81 Abstract quote
Hyperkeratosis of the areola is a rare benign condition of unknown etiology characterized by slowly growing verrucous thickening and brown pigmentation of the areola or/and the nipple. It may be presented as isolated nevoid form or associated with other skin diseases.
We described a 21-year-old woman with characteristic lesions of nevoid hyperkeratosis in both areolas but with histopathological findings resembling mycosis fungoides. Cutaneous lesions have remained unchanged after two years of follow-up.

Hyperkeratosis of the nipple and areola is a rare mamma condition. Typical lesions are characterized by persistent verrucous thickening and dark pigmentation of the nipple or areola (or both) and may occur unilaterally or bilaterally in both sexes.
We report what we believe to be the first therapeutic trial with carbon dioxide laser in a patient with hyperkeratosis areolae mammae naeviformis.
