A middle-aged right-handed housewife presented with complaints of severely painful hand discolouration for 1\u2009week, which usually worsened with cold exposure. She was diagnosed with PsA 6\u2009months earlier. Her PsA was well controlled with weekly methotrexate. Physical examination showed no features of scleroderma or skin necrosis of her right hand. Both radial pulses were strong and symmetrical. Her nailfolds were visibly normal. The extractable nuclear antigen panel and other blood investigations were negative for scleroderma and other possible causes of secondary Raynaud\u2019s phenomenon. Occupational or environmental factors were also excluded. Dermatoscope examination of the nailfolds revealed some areas of dilated capillary loops, areas of vascular sparing and proximal nail fold telangiectasia. The diagnosis of secondary Raynaud\u2019s phenomenon was made, and an oral calcium channel blocker was started. The patient had significant improvement in symptoms shortly afterwards.<\/jats:p>","DOI":"10.1136\/bcr-2023-258215","type":"journal-article","created":{"date-parts":[[2024,3,5]],"date-time":"2024-03-05T12:06:16Z","timestamp":1709640376000},"page":"e258215","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Raynaud\u2019s phenomenon associated with psoriatic arthritis"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1721-6329","authenticated-orcid":false,"given":"Mohd Jazman","family":"Che Rahim","sequence":"first","affiliation":[{"name":"Internal Medicine, Hospital Universiti Sains Malaysia, Kota Bahru, Kelantan, Malaysia"},{"name":"Universiti Sains Malaysia - Kampus Kesihatan, Kota Bharu, Kelantan, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jo Anne","family":"Lim","sequence":"additional","affiliation":[{"name":"Internal Medicine, Hospital Universiti Sains Malaysia, Kota Bahru, Kelantan, Malaysia"},{"name":"Universiti Sains Malaysia - Kampus Kesihatan, Kota Bharu, Kelantan, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7872-4581","authenticated-orcid":false,"given":"Wan Syamimee","family":"Wan Ghazali","sequence":"additional","affiliation":[{"name":"Internal Medicine, Hospital Universiti Sains Malaysia, Kota Bahru, Kelantan, Malaysia"},{"name":"Universiti Sains Malaysia - Kampus Kesihatan, Kota Bharu, Kelantan, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,3,5]]},"reference":[{"key":"2025082802214631000_17.3.e258215.1","doi-asserted-by":"publisher","DOI":"10.1002\/art.21972"},{"issue":"5 Suppl 93","key":"2025082802214631000_17.3.e258215.2","first-page":"S48","article-title":"Disease activity and response assessment in Psoriatic arthritis using the disease activity index for Psoriatic arthritis (DAPSA).
