Although most PanNETs exhibit typical cytological features, uncommon morphological variants occasionally occur. We report the first case of a rhabdoid\u2010type PanNET diagnosed solely by cytology. A 48\u2010year\u2010old woman was incidentally found to have a pancreatic head mass. Endoscopic ultrasound\u2010guided fine\u2010needle aspiration cytology revealed tumor cells with eccentric nuclei, granular chromatin, and prominent eosinophilic intracytoplasmic inclusions, which were highlighted by Giemsa staining. Immunocytochemistry demonstrated strong cytokeratin positivity within the inclusions along with the expression of neuroendocrine markers. This case underscores that rhabdoid\u2010type PanNET can be diagnosed through the cytological identification of distinctive intracytoplasmic inclusions and confirmed by immunocytochemistry. Awareness of this rare phenotype is essential for accurate diagnosis and improved clinicopathological understanding of PanNET variants.<\/jats:p>","DOI":"10.1111\/cyt.70118","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T08:57:56Z","timestamp":1787821076000},"page":"641-647","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cytological Identification of a Rhabdoid Variant of Pancreatic Neuroendocrine Neoplasm"],"prefix":"10.1111","volume":"37","author":[{"given":"Miyu","family":"Okuda","sequence":"first","affiliation":[{"name":"Department of Diagnostic Pathology Kanazawa University Hospital  Kanazawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-2432-5421","authenticated-orcid":false,"given":"Keishi","family":"Mizuguchi","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Pathology Kanazawa University Hospital  Kanazawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsuya","family":"Mori","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Pathology Kanazawa University Hospital  Kanazawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-2307-9251","authenticated-orcid":false,"given":"Urara","family":"Okawa","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Pathology Kanazawa University Hospital  Kanazawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroko","family":"Ikeda","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Pathology Kanazawa University Hospital  Kanazawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,27]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.5858\/133.3.350"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.pas.0000164370.81132.25"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.5858\/arpa.2025-0034-RA"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.2004.018309"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1385\/EP:17:1:75"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00428-018-2398-x"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200402000-00018"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/dc.23892"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200305000-00007"},{"key":"e_1_2_10_11_1","volume-title":"Digestive System Tumours","author":"Board WHOCoTE, International Agency for Research on C","year":"2019"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1530\/EO-25-0065"}],"container-title":["Cytopathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/cyt.70118","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/cyt.70118","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/cyt.70118","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T06:56:57Z","timestamp":1791269817000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/cyt.70118"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8,27]]},"references-count":11,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2026,11]]}},"alternative-id":["10.1111\/cyt.70118"],"URL":"https:\/\/doi.org\/10.1111\/cyt.70118","archive":["Portico"],"relation":{},"ISSN":["0956-5507","1365-2303"],"issn-type":[{"value":"0956-5507","type":"print"},{"value":"1365-2303","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,8,27]]},"assertion":[{"value":"2026-03-26","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-08-22","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-08-27","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
