It usually affects children and young adults, whereas occurrence in older individuals is distinctly uncommon. We report a 53-year-old male laborer who presented with multiple, discrete, erythematous, itchy papuloplaque lesions over the back and neck for 8 days. There were no systemic symptoms. Clinical differentials included pityriasis rosea and PLEVA. Histopathological examination of a punch biopsy revealed mild acanthosis, focal spongiosis, basal layer vacuolar degeneration, lymphocytic exocytosis, red blood cell extravasation, and a dense superficial perivascular lichenoid lymphocytic infiltrate, confirming the diagnosis of PLEVA. The patient responded well to a short course of systemic and topical therapy, with complete resolution of lesions within 6 weeks and no recurrence on follow-up. This case highlights that PLEVA can present even in older adults, an age group where it is exceptionally uncommon. Recognition of its variable clinical spectrum and careful histopathological evaluation are essential to distinguish it from other papulosquamous disorders. Reporting such atypical presentations expands current understanding of disease demographics and reinforces the need to consider PLEVA in the differential diagnosis of acute eruptive dermatoses across all age groups.<\/jats:p>","DOI":"10.4103\/ijabmr.ijabmr_56_26","type":"journal-article","created":{"date-parts":[[2026,6,16]],"date-time":"2026-06-16T15:00:33Z","timestamp":1781622033000},"page":"147-149","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Pityriasis Lichenoides et Varioliformis Acuta: Diagnostic Enigma Unveiled with Clinicopathologic Insights into a Rare Dermatologic Entity"],"prefix":"10.4103","volume":"16","author":[{"given":"Yash","family":"Thesiya","sequence":"first","affiliation":[{"name":"Department of Pathology, Venereology and Leprosy, AIIMS, Rajkot, Gujarat, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Parth","family":"Goswami","sequence":"additional","affiliation":[{"name":"Department of Pathology, Venereology and Leprosy, AIIMS, Rajkot, Gujarat, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Garima","family":"Anandani","sequence":"additional","affiliation":[{"name":"Department of Pathology, Venereology and Leprosy, AIIMS, Rajkot, Gujarat, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yashdeep Singh","family":"Pathania","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Venereology and Leprosy, AIIMS, Rajkot, Gujarat, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,6,16]]},"reference":[{"key":"R1-20260617","doi-asserted-by":"crossref","first-page":"557","DOI":"10.1016\/j.jaad.2005.07.058","article-title":"Pityriasis lichenoides and its subtypes","volume":"55","author":"Bowers","year":"2006","journal-title":"J Am Acad Dermatol"},{"key":"R2-20260617","doi-asserted-by":"crossref","first-page":"398","DOI":"10.4103\/ijdvl.IJDVL_48_18","article-title":"Pityriasis lichenoides et varioliformis acuta following measles rubella vaccine","volume":"86","author":"Shastry","year":"2020","journal-title":"Indian J Dermatol Venereol Leprol"},{"key":"R3-20260617","doi-asserted-by":"crossref","first-page":"473","DOI":"10.1016\/0190-9622(90)70243-B","article-title":"Pityriasis lichenoides in children: A long-term follow-up of eighty-nine cases","volume":"23","author":"Gelmetti","year":"1990","journal-title":"J Am Acad Dermatol"},{"key":"R4-20260617","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1016\/j.jaad.2006.08.023","article-title":"Pityriasis lichenoides in childhood: A retrospective review of 124 patients","volume":"56","author":"Ersoy-Evans","year":"2007","journal-title":"J Am Acad Dermatol"},{"key":"R5-20260617","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1046\/j.1525-1470.1998.1998015001.x","article-title":"Pityriasis lichenoides in children: Clinicopathologic review of 22 patients","volume":"15","author":"Roman\u00ed","year":"1998","journal-title":"Pediatr Dermatol"},{"key":"R6-20260617","doi-asserted-by":"crossref","first-page":"181","DOI":"10.1590\/abd1806-4841.20153492","article-title":"Pityriasis lichenoides et varioliformis acuta after influenza vaccine","volume":"90","author":"Castro","year":"2015","journal-title":"An Bras Dermatol"},{"key":"R8-20260617","doi-asserted-by":"crossref","first-page":"458","DOI":"10.1046\/j.1468-3083.2001.00341.x","article-title":"Pityriasis lichenoides et varioliformis acuta during pregnancy","volume":"15","author":"Brazzini","year":"2001","journal-title":"J Eur Acad Dermatol Venereol"},{"key":"R9-20260617","doi-asserted-by":"crossref","first-page":"46","DOI":"10.1111\/j.1346-8138.1994.tb01409.x","article-title":"Febrile ulceronecrotic Mucha-Habermann's disease","volume":"21","author":"Maekawa","year":"1994","journal-title":"J Dermatol"},{"issue":"Suppl 2","key":"R10-20260617","first-page":"50","article-title":"Febrile ulceronecrotic pityriasis lichenoides et varioliformis acuta","volume":"189","author":"De","year":"1994","journal-title":"Dermatology"},{"key":"R11-20260617","doi-asserted-by":"crossref","first-page":"543","DOI":"10.4103\/2229-5178.193917","article-title":"Salute sign: A nonambiguous histopathological sign in pityriasis rosea","volume":"7","author":"Thomas","year":"2016","journal-title":"Indian Dermatol Online J"},{"key":"R12-20260617","first-page":"36","article-title":"Clinical and histopathological study of 50 cases of lichen planus","volume":"2","author":"Bangaru","year":"2016","journal-title":"IP Indian J Clin Exp Dermatol"}],"container-title":["International Journal of Applied &amp;
