The distribution of diagnoses was lichen sclerosus (<jats:styled-content style=\"fixed-case\">LS<\/jats:styled-content>) in 25\/60 (42%), lichen simplex chronicus (<jats:styled-content style=\"fixed-case\">LSC<\/jats:styled-content>) in 23\/60 (38%), lichen planus (<jats:styled-content style=\"fixed-case\">LP<\/jats:styled-content>) in 10\/60 (17%), and a non\u2010specific lichenoid reaction in 2\/60 (3%). Eleven of 25 cases of LS (44%) showed superimposed <jats:styled-content style=\"fixed-case\">LSC<\/jats:styled-content>. Of 10 <jats:styled-content style=\"fixed-case\">LP<\/jats:styled-content> cases, nine (90%) were hypertrophic and three of these showed pseudoepitheliomatous hyperplasia; none were erosive <jats:styled-content style=\"fixed-case\">LP<\/jats:styled-content>.
