With this study we sought to better characterize <jats:styled-content style=\"fixed-case\">PP<\/jats:styled-content> eruptions, including clinical evolution and management. A retrospective chart review from 2003 to 2013 querying characteristics of children with a biopsy\u2010proven diagnosis of <jats:styled-content style=\"fixed-case\">PP<\/jats:styled-content> in the Centre Hospitalier Universitaire Ste\u2010Justine dermatology clinic (Montreal, Quebec, Canada) was performed. Follow\u2010up was obtained through telephone interviews. Descriptive statistical analysis was used. Of the 17 subjects, 8 were male and the mean age of onset was 9\u00a0years. <jats:styled-content style=\"fixed-case\">PP<\/jats:styled-content> was asymptomatic in 11 patients, pruritic in 3, and of cosmetic concern in 3. Schamberg's disease was the most frequent subtype in 12 cases. Resolution of <jats:styled-content style=\"fixed-case\">PP<\/jats:styled-content> was found in 13 cases with a median duration of less than 1 year (range 6\u00a0months\u20139\u00a0years). Five patients experienced spontaneous clearing without treatment, and improvement was observed in 75% of cases treated with topical corticosteroids and 100% with narrowband ultraviolet B (nb<jats:styled-content style=\"fixed-case\">UVB<\/jats:styled-content>). No associated disease, significant drug exposure, or contact allergens were found. Those findings support that <jats:styled-content style=\"fixed-case\">PP<\/jats:styled-content>s in children are idiopathic, chronic eruptions that can benefit from watchful waiting, although topical corticosteroids or nb<jats:styled-content style=\"fixed-case\">UVB<\/jats:styled-content> are may be useful if the patient or family desires faster resolution. This study was limited by its small size, its retrospective nature, and selection and recall bias.<\/jats:p>","DOI":"10.1111\/pde.12519","type":"journal-article","created":{"date-parts":[[2015,2,18]],"date-time":"2015-02-18T06:53:13Z","timestamp":1424242393000},"page":"358-362","source":"Crossref","is-referenced-by-count":23,"title":["Pigmented
