However, histopathologic characteristics of pancreatic cysts after ablation have not been well-elucidated. &lt;b&gt;&lt;i&gt;Methods:&lt;\/i&gt;&lt;\/b&gt; Here, we analyzed pathological findings of 12 surgically resected pancreatic cysts after EUS-A with ethanol and\/or paclitaxel injection. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; Mean patient age was 49.8 \u00b1 13.6 years with a 0.3 male\/female ratio. Clinical impression before EUS-A was predominantly mucinous cystic neoplasms. Mean cyst size before and after ablation therapy was similar (3.7 \u00b1 1.0 cm vs. 3.4 \u00b1 1.6 cm; &lt;i&gt;p&lt;\/i&gt; = 0.139). Median duration from EUS-A to surgical resection was 18 (range, 1\u201359) months. Mean percentage of the residual neoplastic lining epithelial cells were 23.1 \u00b1 37.0%. Of the resected cysts, 8 cases (67%) showed no\/minimal (&amp;#x3c;5%) residual lining epithelia, while the remaining 4 cases (33%) showed a wide range of residual mucinous epithelia (20\u201390%). Ovarian-type stroma was noted in 5 cases (42%). Other histologic features included histiocytic aggregation (67%), stromal hyalinization (67%), diffuse egg shell-like calcification along the cystic wall (58%), and fat necrosis (8%). &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; Above all, diffuse egg shell-like calcification along the pancreatic cystic walls with residual lining epithelia and\/or ovarian-type stroma were characteristics of pancreatic cysts after EUS-A. Therefore, understanding these histologic features will be helpful for precise pathological diagnosis of pancreatic cystic tumor after EUS-A, even without knowing the patient\u2019s history of EUS-A. <\/jats:p>","DOI":"10.1159\/000518050","type":"journal-article","created":{"date-parts":[[2021,8,26]],"date-time":"2021-08-26T21:00:54Z","timestamp":1630011654000},"page":"49-55","source":"Crossref","is-referenced-by-count":6,"title":["Pancreatic Cysts after Endoscopic Ultrasonography-Guided Ethanol and\/or Paclitaxel Ablation Therapy: Another Mimic of Pancreatic Pseudocysts"],"prefix":"10.1159","volume":"89","author":[{"given":"Soyeon","family":"An","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"You-Na","family":"Sung","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sung Joo","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dong-Wan","family":"Seo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3007-2094","authenticated-orcid":false,"given":"Sun-Young","family":"Jun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seung-Mo","family":"Hong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2021,8,26]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1097\/MOG.0b013e328363e3b3"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.2214\/AJR.07.3340"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.cgh.2010.05.017"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000005535"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1097\/01.sla.0000124299.57430.ce"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.pan.2018.11.014"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/j.path.2016.05.005"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjsurg.2006.02.020"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1097\/01.sla.0000237652.84466.54"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/s0002-9610(99)00186-5"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1038\/ajg.2011.117"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1097\/MPA.0000000000000567"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2010.10.001"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2007.09.038"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.7863\/jum.1998.17.8.531"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.7178\/eus.01.008"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2009.03.1173"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1097\/MPA.0b013e3182128d06"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016\/s0016-5107(05)00320-2"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1055\/s-0034-1365496"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1055\/s-0042-105431"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2017.08.009"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1080\/00365520802495537"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1055\/s-0043-110030"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2016.09.011"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199504133321507"},{"key":"ref27","doi-asserted-by":"publisher","DOI":"10.1111\/his.13897"}],"container-title":["Pathobiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/518050","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/518050","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:10:47Z","timestamp":1745421047000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000518050"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,8,26]]},"references-count":27,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2022,1,18]]},"published-print":{"date-parts":[[2022,1,25]]}},"URL":"https:\/\/doi.org\/10.1159\/000518050","archive":["Portico"],"relation":{},"ISSN":["1015-2008","1423-0291"],"issn-type":[{"value":"1015-2008","type":"print"},{"value":"1423-0291","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,8,26]]}}}
