  METHODS
  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 symptoms occurred, 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.
