NETs, often found in the gastrointestinal tract, can be found anywhere in the body, and have metastatic potential. NETs occasionally present with metastatic disease without an identifiable primary tumor.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case<\/jats:title><jats:p>A 79\u2010year\u2010old female patient presented with an abdominal wall mass. Percutaneous biopsy was consistent with a NET. Preoperative endoscopy and PillCam were unremarkable. PET Dotatate demonstrated uptake in the abdominal wall as well as vague uptake in the pelvis. Intraoperatively, we identified a suspicious nodule on the sigmoid colon, which was consistent with a drop metastasis on final pathology.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In this case report we present a patient with a NET metastasis to the abdominal wall without a known primary site. This case highlights the limitations of endoscopy and imaging in the workup of metastatic NETs. Additionally, this is a novel case report of a metastatic NET to the abdominal wall without an identifiable primary site.<\/jats:p><\/jats:sec>","DOI":"10.1002\/cnr2.1610","type":"journal-article","created":{"date-parts":[[2022,2,10]],"date-time":"2022-02-10T08:45:57Z","timestamp":1644482757000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["An abdominal wall neuroendocrine tumor of unknown primary origin: A case report and review of the literature"],"prefix":"10.1002","volume":"5","author":[{"given":"Olivia","family":"Jagiella\u2010Lodise","sequence":"first","affiliation":[{"name":"Royal College of Surgeons in Ireland Dublin Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valerie","family":"Jagiella","sequence":"additional","affiliation":[{"name":"Digestive Healthcare of Georgia Atlanta Georgia USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2003-2275","authenticated-orcid":false,"given":"Evan","family":"Weitman","sequence":"additional","affiliation":[{"name":"Piedmont Atlanta Hospital, Division of Surgical Oncology &amp; HPB Surgery Atlanta Georgia USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,2,10]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21493"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11154-017-9437-9"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jss.2013.04.008"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPA.0000000000001391"},{"key":"e_1_2_10_6_1","unstructured":"ShahMH GoldnerWS BensonAB et al.
