Mucin deposition is a characteristic finding in skin lesions, but it is rare in other organs. We present a case with erythematous patches from the terminal ileum to the anus in an SLE patient. Diffuse colitis was diagnosed clinically. However, in addition to inflammatory cell infiltration, there was abundant mucinous material deposition in the submucosa. The mucinous material was positive for Alcian blue staining (pH 2.5) and was sensitive to hyaluronidase digestion. These findings are similar to those of cutaneous mucinosis in SLE patients. This is thought to be the first case of gastrointestinal tract mucinosis in SLE reported in the literature.<\/jats:p>","DOI":"10.1177\/10668969231157313","type":"journal-article","created":{"date-parts":[[2023,2,24]],"date-time":"2023-02-24T00:49:55Z","timestamp":1677199795000},"page":"1522-1525","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Intestinal Submucosal Mucinosis in a Patient With Systemic Lupus Erythematosus: A Case Report"],"prefix":"10.1177","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6742-9835","authenticated-orcid":false,"given":"Che-Wei","family":"Hsu","sequence":"first","affiliation":[{"name":"National Cheng Kung University Hospital"},{"name":"National Cheng Kung University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8594-4649","authenticated-orcid":false,"given":"Chien-An","family":"Chu","sequence":"additional","affiliation":[{"name":"National Cheng Kung University Hospital"},{"name":"National Cheng Kung University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6392-2828","authenticated-orcid":false,"given":"Chia-Tse","family":"Weng","sequence":"additional","affiliation":[{"name":"National Cheng Kung University Hospital"},{"name":"National Cheng Kung University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4947-1463","authenticated-orcid":false,"given":"Chung-Ta","family":"Lee","sequence":"additional","affiliation":[{"name":"National Cheng Kung University Hospital"},{"name":"National Cheng Kung University"},{"name":"National Cheng Kung University Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,2,23]]},"reference":[{"key":"e_1_3_2_2_2","first-page":"834291","article-title":"Cutaneous manifestations of systemic lupus erythematosus","volume":"2012","author":"Uva L","year":"2012","unstructured":"Uva L, Miguel D, Pinheiro C, Freitas JP, Marques Gomes M, Filipe P.
