Pleural dedifferentiated liposarcoma: A case report

Complete Resection of a Cavoatrial Metastatic Liposarcoma under Hypothermic Circulatory Arrest

A patient underwent surgical resection twice for primary and metastatic dedifferentiated liposarcomas. Computed tomography revealed a tumor mass at the cavoatrial junction. Prompt surgical resection of the tumor with thrombectomy was successfully performed using cardiopulmonary bypass with hypothermic circulatory arrest. Despite the poor prognosis of metastatic or recurrent liposarcoma, the patient has survived for 8 years since the first tumor resection.

Primary retroperitoneal liposarcoma: a rare case report

Primary retroperitoneal liposarcoma (PRPLS) is a rare malignant tumor with a low incidence. A 34-year-old female patient presented to our department with abdominal pain, nausea, and vomiting for 2 days. Abdominal computed tomography (CT) indicated a huge mass between the liver and kidney, with a clear boundary and measuring approximately 202 mm × 155 mm ×106 mm. The mass was considered a retroperitoneal lipoma or liposarcoma. The entire tumor was completely resected without auxiliary injury, and histopathology of the resected specimen indicated liposarcoma. The patient recovered well and was discharged from our department on the 6th postoperative day. No signs of relapse were seen during 1-year of follow-up. PRPLS is rare and without obvious symptoms in the early stage. CT plays a vital role in the diagnosis of PRPLS, and surgical resection is considered the most suitable treatment. Radiotherapy and chemotherapy might also be treatment options to improve the overall survival of PRPLS patients.
