Recently, reports of the recurrence of needle tract seeding after EUS-FNA are emerging.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case presentation<\/jats:title><jats:p>An 83-year-old woman was referred to our hospital to undergo further examination of her pancreatic tumor. Multidetector computed tomography (MDCT) revealed a 25-mm-diameter mass in the pancreatic body. She underwent EUS-FNA (transgastric, 22-G needle, 2 passes) and was subsequently diagnosed with adenocarcinoma. Distal pancreatosplenectomy followed by adjuvant chemotherapy with S-1 for 6\u2009months was performed. The level of carbohydrate antigen 19\u20139 gradually increased 22\u2009months after surgery, and MDCT, which was performed 3\u2009months later, revealed a 23-mm low-density mass in the stomach and paragastric lymph node swelling. Gastroendoscopy revealed a submucosal tumor, and endoscopic ultrasound revealed a hypoechoic mass in the submucosa of the gastric wall. Partial gastrectomy with lymph node resection was performed. The pathological findings showed adenocarcinoma extending from the subserosa to the submucosa and lymph node metastasis, consistent with a tumor recurrence from the resected pancreatic tumor. She received adjuvant chemotherapy with S-1; recurrence was not observed for 5\u2009months, at the time of this writing.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>It is important to pay careful attention to the development of needle tract seeding in patients with pancreatic cancer diagnosed by EUS-FNA. This is the first case of needle tract seeding with lymph node metastasis, highlighting the need for caution and providing novel insight in the postoperative follow-up of patients with pancreatic body\/tail cancer.<\/jats:p><\/jats:sec>","DOI":"10.1186\/s12876-020-1159-x","type":"journal-article","created":{"date-parts":[[2020,1,15]],"date-time":"2020-01-15T15:02:33Z","timestamp":1579100553000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["Needle tract seeding recurrence of pancreatic cancer in the gastric wall with paragastric lymph node metastasis after endoscopic ultrasound-guided fine needle aspiration followed by pancreatectomy: a case report and literature review"],"prefix":"10.1186","volume":"20","author":[{"given":"Nami","family":"Sato","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6495-0422","authenticated-orcid":false,"given":"Shigetsugu","family":"Takano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideyuki","family":"Yoshitomi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katsunori","family":"Furukawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsukasa","family":"Takayashiki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satoshi","family":"Kuboki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daisuke","family":"Suzuki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nozomu","family":"Sakai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shingo","family":"Kagawa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takashi","family":"Mishima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eri","family":"Nakadai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rintaro","family":"Mikata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoya","family":"Kato","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masayuki","family":"Ohtsuka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,1,15]]},"reference":[{"issue":"7","key":"1159_CR1","doi-asserted-by":"publisher","first-page":"813","DOI":"10.1007\/s11605-007-0151-x","volume":"11","author":"MA Eloubeidi","year":"2007","unstructured":"Eloubeidi MA, Varadarajulu S, Desai S, Shirley R, Heslin MJ, Mehra M, et al.
