Abstract
Nevoid hyperkeratosis of the nipple and areola (NHNA) is a rare, benign, idiopathic condition, which occurs predominantly in women of child-bearing age. It is characterized by asymptomatic, hyperkeratotic, verrucous plaques, and either unilateral or bilateral over the nipple and areola. It has to be differentiated from Darier disease, seborrheic keratosis, atopic dermatitis, Paget's disease, frictional hyperkeratosis, and cutaneous T-cell lymphoma. Fused rete ridges, compact orthohyperkeratosis, and filiform papillomatosis are seen on histopathology. Dermoscopy shows keratotic structureless areas with brownish clods. There is no specific treatment, long-term use of calcipotriol and keratolytic agents for more than 6 months, and surgical therapy is recommended. This case is reported to highlight the use of dermoscopy in the diagnosis of NHNA.
