Extrapulmonary recurrence to the retroperitoneum and abdomen is common in MLS. A pregnant patient was referred to our hospital due to abdominal pain and obstipation. In the past, she had received a multimodal treatment of an MLS of the left dorsal thigh. Now, MRI revealed a 14.6\u00d710.1\u00d712.4 cm-sized tumour adjacent to the uterus with a known twin pregnancy (26th week). We performed surgery under tocolytic therapy. The tumour has been completely removed. The histopathological examination revealed a nodular manifestation of a moderately differentiated MLS arising from the mesentery. Eleven weeks later, our patient delivered healthy twins. This is the first report of surgical resection of MLS during a twin pregnancy. With a multidisciplinary approach and a concerted treatment by surgeons and obstetricians, surgical resection resolved malignant intestinal obstruction and enabled an uncomplicated continuation of pregnancy.<\/jats:p>","DOI":"10.1136\/bcr-2019-229742","type":"journal-article","created":{"date-parts":[[2019,7,9]],"date-time":"2019-07-09T06:11:13Z","timestamp":1562652673000},"page":"e229742","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Malignant intestinal obstruction during twin pregnancy: surgical resection of a myxoid liposarcoma without induction of labour"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3104-8288","authenticated-orcid":false,"given":"Christoph","family":"Paasch","sequence":"first","affiliation":[{"name":"General, Visceral and Oncology Surgery, Helios Klinikum Berlin-Buch, Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annette","family":"Isbruch","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynaecology, Helios Klinikum Berlin-Buch, Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martin W","family":"Strik","sequence":"additional","affiliation":[{"name":"General, Visceral and Oncology Surgery, Helios Klinikum Berlin-Buch, Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Siegel","sequence":"additional","affiliation":[{"name":"General, Visceral and Oncology Surgery, Helios Klinikum Berlin-Buch, Berlin, Germany"},{"name":"Faculty of Health, Witten\/Herdecke University, Witten, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,7,8]]},"reference":[{"key":"2025082804010722000_12.7.e229742.1","first-page":"281","article-title":"Ein Fall von b\u00f6sartigen, zum Theil in der Form des Neuroms auftretenden Fettgeschw\u00fclsten","volume":"11","author":"Virchow","year":"1857","journal-title":"Archiv f\u00fcr Pathologische Anatomie und Physiologie und f\u00fcr Klinische Medicin"},{"key":"2025082804010722000_12.7.e229742.2","first-page":"72","volume-title":"WHO Classification of Tumours of Soft Tissue and Bone","volume":"5","author":"Fletcher","year":"2013"},{"key":"2025082804010722000_12.7.e229742.3","doi-asserted-by":"crossref","first-page":"47","DOI":"10.1097\/01.sla.0000234795.98607.00","article-title":"Subtype specific prognostic nomogram for patients with primary liposarcoma of the retroperitoneum, extremity, or trunk","volume":"244","author":"Dalal","year":"2006","journal-title":"Ann Surg"},{"key":"2025082804010722000_12.7.e229742.4","doi-asserted-by":"crossref","first-page":"103","DOI":"10.1016\/j.otsr.2014.09.024","article-title":"Prognostic factors for the recurrence of myxoid liposarcoma: 20 cases with up to 8 years follow-up","volume":"101","author":"Lemeur","year":"2015","journal-title":"Orthop Traumatol Surg Res"},{"key":"2025082804010722000_12.7.e229742.5","doi-asserted-by":"crossref","first-page":"145","DOI":"10.1186\/s12957-015-0555-0","article-title":"Giant retroperitoneal liposarcoma during pregnancy: a case report","volume":"13","author":"Huo","year":"2015","journal-title":"World J Surg Oncol"},{"key":"2025082804010722000_12.7.e229742.6","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.20.4.g00jl021007"},{"key":"2025082804010722000_12.7.e229742.7","doi-asserted-by":"crossref","unstructured":"Stolte M , R\u00fcschoff J , Kl\u00f6ppel G .
