An unusual pigmented skin lesion on the nipple‐areola area

Abstract

Abstract Considering the rarity and underdiagnoses of this disorder, a pigmented and hyperkeratotic skin lesion located on the trunk, resembling to acanthosis nigricans should always be investigated for terra firma‐forme dermatosis (TFFD) and thus alcohol must be applied. TFFD should be known among dermatologists and can be easily diagnosed and treated with isopropyl alcohol.
