Clinically, PP presents with pruritic, erythematous papules, which eventually form a reticulated pattern and resolve into post\u2010inflammatory hyperpigmentation. The exact pathogenesis of PP remains unclear, but it is frequently linked to ketosis\u2010inducing conditions, including strict dieting, fasting, and metabolic changes, such as those observed in diabetic ketoacidosis or anorexia nervosa. In recent years, PP has been increasingly reported in patients undergoing bariatric surgery, likely due to the rapid weight loss and subsequent ketosis that often follow these procedures. This review aims to take a closer and deeper look at the emerging connection between PP and bariatric surgery, particularly laparoscopic sleeve gastrectomy.<\/jats:p>","DOI":"10.1155\/drp\/1993385","type":"journal-article","created":{"date-parts":[[2026,1,10]],"date-time":"2026-01-10T07:08:11Z","timestamp":1768028891000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Prurigo Pigmentosa Following Bariatric Surgery: A Comprehensive Clinicopathological Review"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-6577-6463","authenticated-orcid":false,"given":"Khalid Nabil","family":"Nagshabandi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulrahman","family":"M.
