He visited hospital with right lower abdominal pain and palpable mass. Laboratory data including tumor markers were within normal limits, and computed tomography revealed a 15 \u00d7 10 cm sized enhancing soft mass. Right hemicolectomy was performed, and after that, a further large retroperitoneal mass was revealed and this was also radically excised. Mixed-type colon liposarcoma and well differentiated type of retroperitoneal liposarcoma were diagnosed in pathologic report. The patient has remained free of disease for 24 months.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>No standardized guidelines have been established for its treatment because too small a number of cases have been reported, but surgical resection was considered the treatment of choice.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1471-2407-10-239","type":"journal-article","created":{"date-parts":[[2010,5,27]],"date-time":"2010-05-27T18:15:08Z","timestamp":1274984108000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Primary liposarcoma of the ascending colon: a rare case of mixed type presenting as hemoperitoneum combined with other type of retroperitoneal liposarcoma"],"prefix":"10.1186","volume":"10","author":[{"given":"Yoon Young","family":"Choi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong Jin","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"So Young","family":"Jin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2010,5,27]]},"reference":[{"key":"2038_CR1","doi-asserted-by":"publisher","first-page":"605","DOI":"10.1097\/00000478-199505000-00016","volume":"19","author":"LG Kindblom","year":"1995","unstructured":"Kindblom LG, Meis-Kindblom JM, Enzinger FM: Variants of liposarcoma.
