Abdominal CT revealed a 25 mm hypodense cystic lesion in the tail of the pancreas. MRI showed a multiloculated cystic lesion, T1-hypointense and T2-hyperintense lesion, without wall enhancement. Endoscopic ultrasound detected a 25 mm multi-loculated cystic lesion, with regular margin and without pancreatic duct communication. Diagnosis of pancreatic mucinous cystadenoma was discussed and the patient was referred to surgery. She underwent distal pancreatectomy with spleen preservation. Pathological examination revealed the diagnosis of pancreatic mesothelial cyst. Histologically, the cyst was multiloculated, lined by cuboidal epithelium, ovoid nuclei and amphophilic cytoplasm, without mucin deposition or cytological atypia. Immunohistochemistry examination revealed positive staining for cytokeratin 5\/6, vimentin and calretinin. At 1-year follow-up, she is in her usual health, without any symptoms.<\/jats:p>","DOI":"10.1136\/bcr-2020-236255","type":"journal-article","created":{"date-parts":[[2020,10,7]],"date-time":"2020-10-07T17:30:39Z","timestamp":1602091839000},"page":"e236255","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Pancreatic mesothelial cyst"],"prefix":"10.1136","volume":"13","author":[{"given":"Charbel","family":"Chater","sequence":"first","affiliation":[{"name":"Department of General Surgery, Notre Dame des Secours University Hospital Center, Jbeil, Mont-Liban, Lebanon"},{"name":"Holy Spirit University of Kaslik Faculty of Medicine and Medical Sciences, Jounieh, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph Obeid","family":"Obeid","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Notre Dame des Secours University Hospital Center, Jbeil, Mont-Liban, Lebanon"},{"name":"Holy Spirit University of Kaslik Faculty of Medicine and Medical Sciences, Jounieh, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seba","family":"Mhanna","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Notre Dame des Secours University Hospital Center, Jbeil, Mont-Liban, Lebanon"},{"name":"Holy Spirit University of Kaslik Faculty of Medicine and Medical Sciences, Jounieh, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,10,7]]},"reference":[{"key":"2025082707201732000_13.10.e236255.1","doi-asserted-by":"publisher","DOI":"10.1159\/000134279"},{"key":"2025082707201732000_13.10.e236255.2","doi-asserted-by":"crossref","first-page":"371","DOI":"10.1016\/j.anndiagpath.2005.11.007","article-title":"Mesothelial cyst of the pancreas","volume":"10","author":"Nicolas","year":"2006","journal-title":"Ann Diagn Pathol"},{"key":"2025082707201732000_13.10.e236255.3","doi-asserted-by":"crossref","first-page":"436","DOI":"10.1016\/j.pan.2013.05.007","article-title":"Imaging of indeterminate pancreatic cystic lesions: a systematic review","volume":"13","author":"Jones","year":"2013","journal-title":"Pancreatology"},{"key":"2025082707201732000_13.10.e236255.4","doi-asserted-by":"crossref","first-page":"415","DOI":"10.1097\/MCG.0000000000001310","article-title":"Management of incidental pancreatic cystic lesions: integrating novel diagnostic and prognostic factors with current clinical guidelines","volume":"54","author":"Kim","year":"2020","journal-title":"J Clin Gastroenterol"},{"key":"2025082707201732000_13.10.e236255.5","doi-asserted-by":"crossref","first-page":"552","DOI":"10.1097\/MPA.0000000000001521","article-title":"Risk factors for pancreatic cancer and the necessity of long-term surveillance in patients with pancreatic cystic lesions","volume":"49","author":"Yoshioka","year":"2020","journal-title":"Pancreas"},{"key":"2025082707201732000_13.10.e236255.6","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.138.4.427"},{"key":"2025082707201732000_13.10.e236255.7","unstructured":"Chen JC , Beal EW , Pawlik TM , et al .
