Oncol.

These can be related to cholesterolosis or conventional adenomas, but occasionally extraordinary findings do emerge. In our case, a 67-year old lady with typical complaints of cholecystitis underwent routine laparoscopic cholecystectomy. Preoperative ultrasound revealed a polypoid mass with inflammation and without suspicion for malignancy. Microscopic examination showed partly conventional, low-grade dysplastic crypts forming a villous and rather complex structure. Ectopic crypt foci, slit-like serration pattern and serrated dysplasia with eosinophylic cytoplasm and centrally located nuclei were seen throughout the lesion, thus a traditional serrated adenoma (TSA) of the gallbladder was diagnosed. TSA represents the rarest subtype of serrated lesions in the colon and extracolonic manifestations are sporadically reported. Until now only a single case of a serrated adenoma was reported from the gallbladder. Here we describe the detailed clinical, pathological and molecular findings of our case and discuss these in the light of current literature data regarding this field.<\/jats:p>","DOI":"10.3389\/pore.2022.1610133","type":"journal-article","created":{"date-parts":[[2022,2,3]],"date-time":"2022-02-03T23:12:16Z","timestamp":1643929936000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Traditional Serrated Adenoma of the Gallbladder, a Case Report"],"prefix":"10.3389","volume":"28","author":[{"given":"Tam\u00e1s","family":"Micsik","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Jakab","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Csaba","family":"Lehoczki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u00c1rp\u00e1d V.","family":"Patai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,2,4]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"218","DOI":"10.1111\/j.1365-2559.2008.03192.x","article-title":"Gallbladder Cancer: a Morphological and Molecular Update","volume":"55","author":"Goldin","year":"2009","journal-title":"Histopathology"},{"key":"B2","doi-asserted-by":"publisher","first-page":"625","DOI":"10.2478\/pjs-2013-0094","article-title":"Laparoscopic Cholecystectomy in the Treatment of Gallbladder Polypoid Lesions - 15 Years of Experience","volume":"85","author":"Mat\u0142ok","year":"2013","journal-title":"Polski przeglad chirurgiczny"},{"key":"B3","first-page":"91","article-title":"Histopathologic Features and Frequency of Gall Bladder Lesions in Consecutive 540 Cholecystectomies","volume":"6","author":"Terada","year":"2013","journal-title":"Int J Clin Exp Pathol"},{"key":"B4","doi-asserted-by":"publisher","first-page":"1506","DOI":"10.1016\/j.humpath.2011.11.011","article-title":"Adenomas of the Gallbladder.
