Ashy dermatosis: A comprehensive review
نویسنده
چکیده
Ashy dermatosis, first described by Ramirez in 1957 [1], is an idiopathic acquired macular hyperpigmentation disorder. The descriptive term “ashy or los cenicientos” was used because of the ashy blue-grey color of the lesions. The sites commonly affected include face, neck, trunk and upper limbs but any region of the body can be affected [2]. Convit, Kerdel-Vegas and Rodriguez in their case series reported the presence of raised erythematous borders in the early stages and proposed the term “erythema dyschromicum perstans (EDP)” [3]. Other authors however have noted that EDP can occur without marginal erythema [4,5]. Bhutani and his colleagues described similar hyperpigmented macules over the flexures and photoexposed areas in 40 Indian patients, about a third of whom had associated features of lichen planus on clinical evaluation and histopathological examination [6]. These entities were subsequently labeled as “lichen planus pigmentosus (LPP)”.
