title: Mycosis fungoides mimicking nevoid hyperkeratosis of the nipple and areola in an adolescent.
abstract: Mycosis fungoides is one of the great imitators in dermatology; it can mimic many dermatoses. Nevoid hyperkeratosis of the nipple and areola is a rare idiopathic disease with typical clinical features of verrucous thickening and brownish discoloration of the nipple, areola or both. Here, a 16-year-old male patient with mycosis fungoides mimicking nevoid hyperkeratosis of the nipple and areola has been reported. To our knowledge, this is the first atypical MF patient to have presented with a NHNA-like lesion. Although the clinical appearance of nevoid hyperkeratosis of the nipple and areola is highly characteristic for diagnosis, histopathological examination is recommended, especially in cases with atypical features such as unexpected age, male gender and unilateral location.
