The most common location of liposarcoma is in the extremities, followed by retroperitoneum, with the bone and trunk being the less frequent presentations. The most common histological subtype is well-differentiated liposarcoma, which has the highest local recurrence, is slow-growing, and is insensitive to chemo and radiotherapy. We present the case of a 62-year-old male patient with a 10-year-growth mass in the dorsal region. A computed tomography scan showed a huge mass in the right dorsal space with a malignant lipomatous appearance, which required surgical removal of a mass of 2,800 g.<\/jats:p>","DOI":"10.3897\/folmed.66.e125471","type":"journal-article","created":{"date-parts":[[2024,11,6]],"date-time":"2024-11-06T15:48:51Z","timestamp":1730908131000},"page":"749-754","source":"Crossref","is-referenced-by-count":0,"title":["Giant dorsal liposarcoma in an elderly man: a case report"],"prefix":"10.3897","volume":"66","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6615-1413","authenticated-orcid":true,"given":"Daniela","family":"Arias-Mari\u00f1o","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-5990-106X","authenticated-orcid":true,"given":"Alejandro","family":"Rojas-Urrea","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-3771-0266","authenticated-orcid":true,"given":"Diego","family":"Herrera-Salcedo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9557-0900","authenticated-orcid":true,"given":"Lorena","family":"Garc\u00eda-Agudelo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2258","published-online":{"date-parts":[[2024,10,31]]},"reference":[{"key":"125471_B1","doi-asserted-by":"crossref","unstructured":"1.
