Although histopathology remains the gold standard, it may not be feasible at times, especially in children. Being noninvasive, dermoscopy can be of great diagnostic importance in such a scenario. Dermoscopy overcomes the refractive properties of stratum corneum by interface medium or cross-polarization enabling easier visualization of lesions.\r\nObjective: To study the dermoscopic features of PRP and compare them with dermoscopic features of psoriasis.\r\nPatients and Methods: Retrospective observational analysis of dermoscopic characteristics of 28 patients with PRP (16) and psoriasis (12). Polarized dermoscopy at 10\u00d7 magnification was performed and photographs were captured by Apple iPhone 7. The selection of dermoscopic variables was based on preexisting literature on the dermoscopic patterns of the 2 entities.\r\nResults: The most frequent dermoscopic criteria of PRP were the presence of a central hair (16\/16; 100%), follicular plugs (11\/16; 68.7%), and perifollicular yellow\/orange halos (9\/16; 56.2%). No vascular structures were seen in our cases of PRP. Psoriasis was characterized by regularly distributed dotted vessels (12\/12; 100%) and white scales (8\/12; 66.6%).\r\nConclusions: Round-to-oval yellowish areas surrounding a central hair with or without follicular plugs represents the most frequent dermoscopic pattern of PRP.<\/jats:p>","DOI":"10.5826\/dpc.0804a10","type":"journal-article","created":{"date-parts":[[2019,4,8]],"date-time":"2019-04-08T20:12:17Z","timestamp":1554754337000},"page":"299-302","source":"Crossref","is-referenced-by-count":14,"title":["Differentiation of pityriasis rubra pilaris from plaque psoriasis by dermoscopy"],"prefix":"10.5826","author":[{"given":"Abhijeet Kumar","family":"Jha","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aimilios","family":"Lallas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sidharth","family":"Sonthalia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deepak","family":"Jakhar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uday K.","family":"Udayan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
