Although paragangliomas can occur anywhere paraganglia are present, they tend to occur in the head, neck, and retroperitoneum. Rarely, paragangliomas can occur in the peripancreatic area and present as a pancreatic mass, creating a diagnostic challenge for the clinician, radiologist, and pathologist. Here, we present a case of a 70\u2010year\u2010old woman with history of breast carcinoma who presented with chronic constipation, early satiety, and an abdominal mass. Her first abdominal CT described a 3.6 cm \u00d7 5 cm \u00d7 4.5 cm cystic and solid mass involving the pancreatic tail that was suspicious for a pancreatic neoplasm. A subsequent abdominal CT described a 5.9 cm multilobulated solid and cystic lesion close to the pancreatic tail. Endoscopic ultrasound\u2010guided fine\u2010needle aspirate of the mass demonstrated scant to moderate cellularity of a heterogeneous population of atypical cells, some with epithelioid morphology and others appearing neuroendocrine\u2010like. By morphology and immunohistochemical stains, an extra\u2010adrenal paraganglioma or pheochromocytoma was considered as a possible diagnosis. The surgical resection specimen confirmed the diagnosis of paraganglioma. This case demonstrates the importance of awareness of paragangliomas in the differential diagnosis of a fine\u2010needle aspiration of a pancreatic mass to avoid erroneous diagnosis.<\/jats:p>","DOI":"10.1002\/dc.23974","type":"journal-article","created":{"date-parts":[[2018,6,8]],"date-time":"2018-06-08T02:16:46Z","timestamp":1528424206000},"page":"804-806","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Diagnosis of paraganglioma as a pancreatic mass: A case report"],"prefix":"10.1002","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4771-3708","authenticated-orcid":false,"given":"Elise","family":"Nguyen","sequence":"first","affiliation":[{"name":"Department of Pathology and Laboratory Medicine University of California Irvine California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manando","family":"Nakasaki","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine University of California Irvine California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas K.","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine University of California Irvine California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Di","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine University of California Irvine California"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,6,7]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPA.0b013e3181ebb4f0"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/dc.23761"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e3182281767"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/modpathol.2013.76"}],"container-title":["Diagnostic Cytopathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fdc.23974","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/dc.23974","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,16]],"date-time":"2023-09-16T09:14:29Z","timestamp":1694855669000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/dc.23974"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,6,7]]},"references-count":4,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2018,9]]}},"alternative-id":["10.1002\/dc.23974"],"URL":"https:\/\/doi.org\/10.1002\/dc.23974","archive":["Portico"],"relation":{},"ISSN":["8755-1039","1097-0339"],"issn-type":[{"value":"8755-1039","type":"print"},{"value":"1097-0339","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,6,7]]},"assertion":[{"value":"2018-02-21","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-05-03","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2018-06-07","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
