Whether this lesion is truly hamartomatous or represents a \u201cburnt-out\u201d phase of varying chronic pathologies has been debated since that time. Examples of NMVH-like proliferations have been reported in the setting of diaphragm disease, Crohn\u2019s disease, radiation, and ischemia. Herein we present the case of a 73-year-old female with partial small bowel obstruction and a past surgical history significant for cholecystectomy and abdominal hysterectomy. A computed tomography scan revealed an ill-defined mass with the same density as muscle extending into the mesentery, worrisome for malignancy and generating the differential of lymphoma versus metastatic disease. Upon laparotomy, a 2.5 cm, constrictive, predominantly mural-based mass was identified. The more proximal bowel was dilated, and there were dense serosal adhesions. Grossly, the transmural lesion had a tan-yellow cobweb-like cut surface and the overlying mucosa was flattened. Histologically, the lesion contained fascicles of smooth muscle, irregularly spaced large nerve bundles, and thick-walled vasculature in a haphazard arrangement within a hypocellular fibroadipose stroma. No stigmata of Crohn\u2019s disease were observed, and the uninvolved enteric tissue was unremarkable. The patient\u2019s medical history was negative for chronic nonsteroidal anti-inflammatory use and was otherwise unremarkable. This case of an NMVH-like lesion is presented as a reminder of benign mass-forming lesions causing bowel obstruction and suggests that such lesions may develop secondary to a chronic inflammatory process.<\/jats:p>","DOI":"10.1177\/1066896915600518","type":"journal-article","created":{"date-parts":[[2015,8,14]],"date-time":"2015-08-14T21:44:11Z","timestamp":1439588651000},"page":"673-676","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Neuromuscular and Vascular Hamartoma of the Small Intestine"],"prefix":"10.1177","volume":"23","author":[{"given":"Jessica W.","family":"Crothers","sequence":"first","affiliation":[{"name":"University of Vermont Medical Center, Burlington, VT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maryam","family":"Zenali","sequence":"additional","affiliation":[{"name":"University of Vermont College of Medicine, Burlington, VT, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,8,14]]},"reference":[{"key":"bibr1-1066896915600518","doi-asserted-by":"publisher","DOI":"10.1136\/jclinpath-2013-201913"},{"key":"bibr2-1066896915600518","doi-asserted-by":"publisher","DOI":"10.1136\/gut.27.8.964"},{"key":"bibr3-1066896915600518","doi-asserted-by":"publisher","DOI":"10.1186\/1477-7819-7-92"},{"key":"bibr4-1066896915600518","doi-asserted-by":"publisher","DOI":"10.1136\/gut.23.11.1008"},{"key":"bibr5-1066896915600518","doi-asserted-by":"publisher","DOI":"10.1136\/gut.28.12.1663"},{"key":"bibr6-1066896915600518","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199911000-00013"},{"key":"bibr7-1066896915600518","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.41.5.516"},{"key":"bibr8-1066896915600518","doi-asserted-by":"publisher","DOI":"10.1002\/gcc.2870120310"},{"key":"bibr9-1066896915600518","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2559.2011.03911.x"}],"container-title":["International Journal of Surgical Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896915600518","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1066896915600518","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1066896915600518","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:20:41Z","timestamp":1777458041000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1066896915600518"}},"subtitle":["An Exuberant Reparative Process Secondary to Chronic Inflammation"],"short-title":[],"issued":{"date-parts":[[2015,8,14]]},"references-count":9,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2015,12]]}},"alternative-id":["10.1177\/1066896915600518"],"URL":"https:\/\/doi.org\/10.1177\/1066896915600518","relation":{},"ISSN":["1066-8969","1940-2465"],"issn-type":[{"value":"1066-8969","type":"print"},{"value":"1940-2465","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,8,14]]}}}
