We aim to describe clinical characteristics of patients with severe gastrointestinal involvement related to dermatomyositis in our center and medical literature. We retrospectively analysed these patients in our center, including cases of erosions\/ulcers, perforation or digestive bleeding. Reported cases from April 1990 to April 2021 were reviewed through PubMed and Cochrane. From our cohort (n = 188), only 3 presented gastrointestinal compromise. All were women (10, 46 and 68 years). The initial symptom was abdominal pain and all had \u22652 episodes of digestive bleeding. All died due to complications of gastrointestinal involvement. Available pathological samples showed vascular ectasia. From the literature review (n = 50), 77% were women with a mean age of 49 years and the main symptom was abdominal pain (65%). All presented active muscular and cutaneous involvement at complication diagnosis. Mortality was 41.7%. The underlying lesion was perforation or ulcer (n = 22), intestinal wall thickening (n = 2), macroscopic inflammation (n = 2) or intestinal pneumatosis (n = 15). In 13 cases, vasculitis was described. Gastrointestinal involvement in dermatomyositis denotes severity, so an early intensive treatment is recommended. Pathological findings suggest that the underlying pathophysiological mechanism is a vasculopathy and not a true vasculitis.<\/jats:p>","DOI":"10.3390\/diagnostics12051200","type":"journal-article","created":{"date-parts":[[2022,5,11]],"date-time":"2022-05-11T10:19:46Z","timestamp":1652264386000},"page":"1200","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Gastrointestinal Involvement in Dermatomyositis"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9184-8079","authenticated-orcid":false,"given":"Ana","family":"Matas-Garcia","sequence":"first","affiliation":[{"name":"Muscle Research Unit, Department of Internal Medicine, Hospital Cl\u00ednic de Barcelona, Universidad de Barcelona, Center for Biomedical Research on Rare Diseases (CIBERER), 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 C.","family":"Milisenda","sequence":"additional","affiliation":[{"name":"Muscle Research Unit, Department of Internal Medicine, Hospital Cl\u00ednic de Barcelona, Universidad de Barcelona, Center for Biomedical Research on Rare Diseases (CIBERER), 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1336-0163","authenticated-orcid":false,"given":"Gerard","family":"Espinosa","sequence":"additional","affiliation":[{"name":"Department of Autoimmune Diseases, Hospital Cl\u00ednic de Barcelona, Universitat de Barcelona, 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3063-0110","authenticated-orcid":false,"given":"M\u00edriam","family":"Cuatrecasas","sequence":"additional","affiliation":[{"name":"Department of Pathology, Hospital Cl\u00ednic de Barcelona, 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2823-9761","authenticated-orcid":false,"given":"Albert","family":"Selva-O\u2019Callaghan","sequence":"additional","affiliation":[{"name":"Systemic Autoimmune Diseases Unit, Hospital Universitari Vall d\u2019Hebron (HVH), Universitat Aut\u00f2noma de Barcelona, 08035 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josep Mar\u00eda","family":"Grau","sequence":"additional","affiliation":[{"name":"Muscle Research Unit, Department of Internal Medicine, Hospital Cl\u00ednic de Barcelona, Universidad de Barcelona, Center for Biomedical Research on Rare Diseases (CIBERER), 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3179-597X","authenticated-orcid":false,"given":"Sergio","family":"Prieto-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Muscle Research Unit, Department of Internal Medicine, Hospital Cl\u00ednic de Barcelona, Universidad de Barcelona, Center for Biomedical Research on Rare Diseases (CIBERER), 08036 Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"971","DOI":"10.1016\/S0140-6736(03)14368-1","article-title":"Polymyositis and dermatomyositis","volume":"362","author":"Dalakas","year":"2003","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"344","DOI":"10.1056\/NEJM197502132920706","article-title":"Polymyositis and Dermatomyositis","volume":"292","author":"Bohan","year":"1975","journal-title":"N.
