Nail psoriasis can have a significant adverse impact on quality of life. However, nail psoriasis is often refractory to both local and systemic therapies, making it challenging to treat. Topical and oral phosphodiesterase-4 inhibitors have been successfully used to treat multiple different subtypes of psoriasis. Topical roflumilast, a phosphodiesterase-4 inhibitor cream, has recently received United States Food and Drug Administration and Health Canada approval for the treatment of plaque psoriasis. In this case report, a 25-year-old female with a 20-year history of nail psoriasis achieved complete resolution of her onychodystrophy after 5 months of daily application of topical roflumilast, without experiencing any side effects. This case report suggests that topical roflumilast may be a useful and well-tolerated therapy for psoriatic nails. <\/jats:p>","DOI":"10.1177\/2050313x241289594","type":"journal-article","created":{"date-parts":[[2024,10,22]],"date-time":"2024-10-22T16:42:53Z","timestamp":1729615373000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Successful treatment of nail psoriasis with topical roflumilast: A case report"],"prefix":"10.1177","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0994-1603","authenticated-orcid":false,"given":"Leah A","family":"Johnston","sequence":"first","affiliation":[{"name":"Cumming School of Medicine, University of Calgary, Calgary, AB, Canada"},{"name":"Faculty of Medicine, University of Ottawa, Ottawa, ON, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan M","family":"Poelman","sequence":"additional","affiliation":[{"name":"Division of Dermatology, University of Calgary, Calgary, AB, Canada"},{"name":"Beacon Dermatology, Calgary, AB, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,10,22]]},"reference":[{"key":"bibr1-2050313X241289594","doi-asserted-by":"publisher","DOI":"10.1002\/acr.23743"},{"key":"bibr2-2050313X241289594","doi-asserted-by":"publisher","DOI":"10.1590\/abd1806-4841.20153736"},{"key":"bibr3-2050313X241289594","doi-asserted-by":"publisher","DOI":"10.1016\/j.jdermsci.2012.11.002"},{"key":"bibr4-2050313X241289594","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2230.2009.03410.x"},{"key":"bibr5-2050313X241289594","doi-asserted-by":"publisher","DOI":"10.1016\/j.tice.2021.101675"},{"key":"bibr6-2050313X241289594","doi-asserted-by":"publisher","DOI":"10.2147\/DDDT.S136986"},{"key":"bibr7-2050313X241289594","doi-asserted-by":"publisher","DOI":"10.1111\/jdv.13970"},{"key":"bibr8-2050313X241289594","doi-asserted-by":"publisher","DOI":"10.2174\/1872211313666191030155837"},{"key":"bibr9-2050313X241289594","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaad.2023.11.024"},{"issue":"5","key":"bibr10-2050313X241289594","first-page":"1","volume":"28","author":"O\u2019Toole A","year":"2023","journal-title":"Skin Ther Lett"},{"key":"bibr11-2050313X241289594","unstructured":"PrZORYVE\u2122 (Roflumilast cream, 0.3% w\/w, topical).
