PEComa in the colon is very rare, with only a few reported cases so far. Because of its rarity, the clinical features and biological behavior of PEComa in the colon have yet to be established. A 16-year-old female patient with PEComa in the transverse colon was referred to our hospital for rectal bleeding. Laboratory data showed a hemoglobin level of 6.6 g\/dL, WBC of 8,800\/mm\n                    <jats:sup>3<\/jats:sup>\n                    , and platelet count of 191,000\/mm\n                    <jats:sup>3<\/jats:sup>\n                    . Colonoscopy, barium enema, and abdominal computed tomography revealed a 2-cm, smooth-surfaced, round tumor with focal ulceration in the proximal transverse colon. The patient complained of abdominal pain one day after endoscopic polypectomy. She underwent a segmental resection for a perforated transverse colon. Immunohistochemically, the tumor cells showed strong diffuse positivity for HMB-45 while they were negative for c-kit, smooth muscle actin, cytokeratin, S-100, vimentin, desmin, chromogranin, synaptophysin, EMA, and CD-34. The diagnosis of PEComa was based on histological and immunohistochemical staining. The patient did not receive any adjuvant therapy and was discharged on postoperative day 11 without complications. Whole-body fluorine-18 fluorodeoxyglucose fusion positron emission tomography performed 2 months after surgery showed no signs of recurrence or metastasis. There was also no recurrence or metastasis at 24 months' follow-up.\n                  <\/jats:p>","DOI":"10.1177\/030089160709300120","type":"journal-article","created":{"date-parts":[[2018,2,27]],"date-time":"2018-02-27T03:50:41Z","timestamp":1519703441000},"page":"106-108","source":"Crossref","is-referenced-by-count":39,"title":["Perivascular Epithelioid Cell Tumor (Pecoma) in the Transverse Colon of an Adolescent: A Case Report"],"prefix":"10.1177","volume":"93","author":[{"given":"Jeong-Heum","family":"Baek","sequence":"first","affiliation":[{"name":"Department of Surgery Gachon Medical School, Gil Medical Center, Incheon, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moon","family":"Gi Chung","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine Gachon Medical School, Gil Medical Center, Incheon, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong","family":"Hae Jung","sequence":"additional","affiliation":[{"name":"Department of Pathology, Gachon Medical School, Gil Medical Center, Incheon, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae Hwan","family":"Oh","sequence":"additional","affiliation":[{"name":"Department of Surgery Gachon Medical School, Gil Medical Center, Incheon, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2007,1,1]]},"reference":[{"key":"bibr1-030089160709300120","first-page":"221","volume-title":"Pathology and genetics of tumors of soft tissue and bone","author":"Folpe A.L.","year":"2002"},{"key":"bibr2-030089160709300120","doi-asserted-by":"publisher","DOI":"10.1007\/s10350-004-0637-5"},{"key":"bibr3-030089160709300120","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199203000-00013"},{"key":"bibr4-030089160709300120","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199606000-00010"},{"key":"bibr5-030089160709300120","first-page":"1132","volume":"12","author":"Maluf H.","year":"1999","journal-title":"Mod Pathol"},{"key":"bibr6-030089160709300120","doi-asserted-by":"publisher","DOI":"10.1186\/1477-7819-3-25"},{"key":"bibr7-030089160709300120","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.56.8.627"},{"key":"bibr8-030089160709300120","doi-asserted-by":"publisher","DOI":"10.1038\/modpathol.3880351"},{"key":"bibr9-030089160709300120","first-page":"163","volume":"20","author":"D'Andrea V.","year":"1999","journal-title":"G Chir"},{"key":"bibr10-030089160709300120","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2559.1998.0415g.x"}],"container-title":["Tumori Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/030089160709300120","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/030089160709300120","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T18:28:58Z","timestamp":1777660138000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/030089160709300120"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,1]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2007,1]]}},"alternative-id":["10.1177\/030089160709300120"],"URL":"https:\/\/doi.org\/10.1177\/030089160709300120","relation":{},"ISSN":["0300-8916","2038-2529"],"issn-type":[{"value":"0300-8916","type":"print"},{"value":"2038-2529","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,1]]}}}
