Despite its prevalence and benign nature, there are still times when this common disorder presents in an uncommon way or course posing diagnostic or management problems for the treating physician. The etiopathogenesis of PR has always been a dilemma, and extensive research is going on to elicit the exact cause. This review focuses mainly on the difficult aspects of this benign common disorder such as etiopathogenesis, atypical manifestations, recurrent cases, differential diagnosis, therapy and pregnancy considerations. Although we could not find a black and white solution to all these problems, we have tried to compile the related literature to draw out some conclusions.<\/jats:p>","DOI":"10.4103\/0019-5154.185699","type":"journal-article","created":{"date-parts":[[2016,7,12]],"date-time":"2016-07-12T00:18:48Z","timestamp":1468282728000},"page":"375-384","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":50,"title":["Pityriasis Rosea: An Update on Etiopathogenesis and Management of Difficult Aspects"],"prefix":"10.4103","volume":"61","author":[{"given":"Khushbu","family":"Mahajan","sequence":"first","affiliation":[{"name":"From the Department of Dermatology, North Delhi Municipal Corporation Medical College, Hindu Rao Hospital, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vineet","family":"Relhan","sequence":"additional","affiliation":[{"name":"Maulana Azad Medical College, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aditi Kochhar","family":"Relhan","sequence":"additional","affiliation":[{"name":"South Delhi MCD Hospital, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vijay Kumar","family":"Garg","sequence":"additional","affiliation":[{"name":"Maulana Azad Medical College, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-20250605","doi-asserted-by":"crossref","first-page":"20","DOI":"10.1001\/jama.1903.04470030024006","article-title":"Pityriasis rosea \u2013 An erythematous eruption of internal origin","volume":"41","author":"Weiss","year":"1903","journal-title":"JAMA"},{"key":"R2-20250605","doi-asserted-by":"crossref","first-page":"325","DOI":"10.1586\/edm.10.28","article-title":"Current trends in pityriasis rosea","volume":"5","author":"Zawar","year":"2010","journal-title":"Expert Rev Dermatol"},{"key":"R3-20250605","doi-asserted-by":"crossref","first-page":"381","DOI":"10.1017\/S0950268804002304","article-title":"Pityriasis rosea \u2013 Evidence for and against an infectious aetiology","volume":"132","author":"Chuh","year":"2004","journal-title":"Epidemiol Infect"},{"issue":"2 Pt 1","key":"R4-20250605","doi-asserted-by":"crossref","first-page":"241","DOI":"10.1016\/S0190-9622(00)90132-4","article-title":"Erythromycin in pityriasis rosea: A double-blind, placebo-controlled clinical trial","volume":"42","author":"Sharma","year":"2000","journal-title":"J Am Acad Dermatol"},{"key":"R5-20250605","doi-asserted-by":"crossref","first-page":"171","DOI":"10.4103\/0019-5154.44787","article-title":"Study of role of streptococcal throat infection in pityriasis rosea","volume":"53","author":"Parija","year":"2008","journal-title":"Indian J Dermatol"},{"key":"R6-20250605","doi-asserted-by":"crossref","first-page":"374","DOI":"10.1159\/000245991","article-title":"Human herpesvirus 7 in patients with pityriasis rosea.
