ABSTRACT

Background: Soft tissue sarcomas have an incidence rate of 1.8 to 5 cases per year. Of those cases 50% are located in the extremities and 40% are located in the trunk and retroperitoneum. Primary mediastinal liposarcomas represent less than 1% of mediastinal tumors.
Clinical case: A 53 year old female, native and resident of Tabasco, with a history of anterior mediastinal tumor was treated with resection at the National Institute of Cancerology about 16 years ago with histopathological diagnosis of pleomorphic liposarcoma. She started her condition with chest pain, cough and hyaline expectoration, managed as pneumonia in her unit. Other simptoms occured, moderate exertion dyspnea and edema of lower limbs, chest computed tomography prompted for documenting mediastinal tumor measured to be 9 × 9 cm and sent to our unit which is managed with resection.
Conclusion: Liposarcomas represent less than 1% of mediastinal tumors. They require long-term monitoring, given its high recurrence after a long disease-free period.
