Pathological examination showed hydropic degeneration of the basal layer, pigmentary incontinence and moderate inflammatory lymphocytic infiltrate in the dermis. Lichen planus pigmentosus inversus is a rare subtype of lichen planus characterized by hyperchromic, asymptomatic or mildly pruritic macules, measuring from millimeters to centimeters in diameter, with defined borders, affecting intertriginous areas, most commonly in the axillae and groin of Caucasian patients. It presents unique lichenoid histology. We report a case with typical clinical features, histology and evolution.<\/jats:p>","DOI":"10.1590\/abd1806-4841.20132599","type":"journal-article","created":{"date-parts":[[2014,1,30]],"date-time":"2014-01-30T19:47:20Z","timestamp":1391111240000},"page":"146-149","source":"Crossref","is-referenced-by-count":28,"title":["Lichen planus pigmentosus inversus"],"prefix":"10.1590","volume":"88","author":[{"given":"Hugo Rocha","family":"Barros","sequence":"first","affiliation":[{"name":"Brazilian Society of Internal Medicine; Lus\u00edada University Center, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Roberto Paes de","family":"Almeida","sequence":"additional","affiliation":[{"name":"S\u00e3o Paulo Federal University; Lus\u00edada University Center, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra Lopes Mattos e","family":"Dinato","sequence":"additional","affiliation":[{"name":"S\u00e3o Paulo University; Lus\u00edada University Center, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angelo","family":"Sementilli","sequence":"additional","affiliation":[{"name":"S\u00e3o Paulo Federal University; Lus\u00edada University Center, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ney","family":"Romiti","sequence":"additional","affiliation":[{"name":"Lus\u00edada University Center, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"11","DOI":"10.5070\/D356C7H5NT","article-title":"Lichen planus pigmentosus-inversus: Case report and review of an unusual entity","volume":"18","author":"Gaertner E","year":"2012","journal-title":"Dermatol Online J"},{"key":"ref2","series-title":"Rook\/ Wilkinson\/ Ebling.
