The term intends to include diseases previously described in the literature as lichen planus pigmentosus, Riehl's melanosis\/pigmented cosmetic dermatitis and ashy dermatosis\/erythema dyschromicum perstans. The nomenclature and origin of these disorders have always been a matter of discussion. These disorders share many clinicopathological similarities, are difficult to treat and adversely affect the quality of life. Recent consensus points towards the need for a unifying term to facilitate research and therapeutic trials. This article aims to provide a comprehensive review of the recent advances in ADMH.<\/jats:p>","DOI":"10.4103\/idoj.idoj_881_20","type":"journal-article","created":{"date-parts":[[2021,8,2]],"date-time":"2021-08-02T05:38:04Z","timestamp":1627882684000},"page":"663-673","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":44,"title":["Acquired
