We report a case of a 67-year-old male who presented with epigastric pain. CT imaging and cholangiopancreatography were concerning for pancreatic neoplasia. Upper endoscopic ultrasound-guided fine needle aspiration cytology of a perigastric lymph node confirmed metastatic adenocarcinoma of pancreatic origin, and cocci arranged in a tetrad fashions characteristic of Sarcina ventriculi were noted. To our knowledge, this is the first reported case of Sarcina ventriculi in an FNA of metastatic pancreatic carcinoma in a perigastric lymph node. These organisms likely represent carry-through contaminants from the transgastric approach of the endoscopic FNA.<\/jats:p>","DOI":"10.1155\/2021\/4933279","type":"journal-article","created":{"date-parts":[[2021,12,29]],"date-time":"2021-12-29T18:36:39Z","timestamp":1640802999000},"page":"1-5","source":"Crossref","is-referenced-by-count":3,"title":["Sarcina ventriculi in an Endoscopic Ultrasound-Guided Fine Needle Aspiration of a Perigastric Lymph Node with Metastatic Pancreatic Adenocarcinoma: A Carry-Through Contaminant Bacterial Microorganism from the Stomach"],"prefix":"10.1155","volume":"2021","author":[{"given":"Bharat","family":"Nandakumar","sequence":"first","affiliation":[{"name":"Division of Hematology, Mayo Clinic, Rochester, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diva R.","family":"Salomao","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas A.","family":"Boire","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Audrey N.","family":"Schuetz","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0153-498X","authenticated-orcid":true,"given":"Charles D.","family":"Sturgis","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1177\/0036933020912329"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1177\/1066896915610196"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1128\/br.34.1.82-97.1970"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1128\/jb.79.6.857-859.1960"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1128\/jb.171.7.3775-3781.1989"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1309\/CDFF04HE9FHDQPAN"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2010.02.021"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v19.i14.2282"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1007\/BF00590176"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1136\/vr.163.13.391"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1099\/00222615-4-3-343"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0b013e31822911e6"},{"issue":"4","key":"13","first-page":"495","article-title":"Gastric Sarcina ventriculi: incidental or pathologic?","volume":"28","author":"A.
