She did not report any systemic symptoms. On examination, an exophytic mass was observed around her ileostomy and hard lymph nodes palpated in her groins bilaterally. Punch biopsy of the lesion established a diagnosis of invasive melanoma. Positron emission tomography revealed regional metastatic lymphadenopathy in the right axilla and both groins. There was no evidence of distant metastatic disease. The patient then underwent wide local excision of her ileostomy with bowel resection and ileostomy re-siting, bilateral complete ilioinguinal lymphadenectomy and a right Level III axillary dissection. She is doing well postoperatively and receiving adjuvant systemic therapy with BRAF and MEK inhibitors, now 17 months later with no signs of recurrent disease.<\/jats:p>","DOI":"10.1136\/bcr-2019-230265","type":"journal-article","created":{"date-parts":[[2019,8,1]],"date-time":"2019-08-01T11:24:05Z","timestamp":1564658645000},"page":"e230265","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Malignant melanoma arising from an end ileostomy"],"prefix":"10.1136","volume":"12","author":[{"given":"Richard William Donald","family":"Gilbert","sequence":"first","affiliation":[{"name":"General Surgery, Ottawa General Hospital, Ottawa, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harry Myles","family":"Harvey","sequence":"additional","affiliation":[{"name":"Department of Medicine, Royal College of Surgeons in Ireland, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carolyn","family":"Nessim","sequence":"additional","affiliation":[{"name":"General Surgery, Ottawa General Hospital, Ottawa, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,8,1]]},"reference":[{"key":"2025082713080070000_12.7.e230265.1","doi-asserted-by":"crossref","first-page":"391","DOI":"10.1007\/s00384-010-1004-8","article-title":"Stomal melanoma--myth or reality?","volume":"26","author":"Warrier","year":"2011","journal-title":"Int J Colorectal Dis"},{"key":"2025082713080070000_12.7.e230265.2","doi-asserted-by":"crossref","first-page":"e354","DOI":"10.1016\/j.bjps.2012.09.009","article-title":"A rare case of primary malignant melanoma in an ileostomy","volume":"65","author":"Chan","year":"2012","journal-title":"Journal of Plastic, Reconstructive & Aesthetic Surgery"},{"key":"2025082713080070000_12.7.e230265.3","doi-asserted-by":"publisher","DOI":"10.1007\/s10350-007-9188-x"},{"key":"2025082713080070000_12.7.e230265.4","doi-asserted-by":"crossref","first-page":"205","DOI":"10.1016\/0016-5085(88)90313-7","article-title":"Carcinoma developing in ileostomies after 25 or more years","volume":"95","author":"Suarez","year":"1988","journal-title":"Gastroenterology"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2019-230265","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T20:08:10Z","timestamp":1756325290000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2019-230265"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,7]]},"references-count":4,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2019,8,1]]},"published-print":{"date-parts":[[2019,7]]}},"alternative-id":["10.1136\/bcr-2019-230265"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2019-230265","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2019,7]]}}}
