title: Nevoid hyperkeratosis of the areola with histopathological features mimicking mycosis fungoides.
abstract: 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.
