Abstract
This is a case report of a patient with liposaroma of the anterior chest wall. Liposarcoma can potentialy evolve in any part of the body, but that of the chest wall has been rare, as malignant tumors of the chest wall are few. We report a case of a liposarcoma of the anterior chest wall where the differential diagnosis from mammary gland tumor was difficult before the operation. A 57-year-old-woman presented to the hospital with a anterior chest wall tumor which was progressive in size. She was admitted for an operation. A tumor of the left anterior chest wall was smooth, soft, and fixed, and the margin was clear. An operation was performed under the diagnosis of either chest wall or mammary gland tumor. Two giant neoplasms with capsules wesl located under the pectoralis major and fixed to the mammary gland. An extirpation was performed. The size of the giant tumors was 24×17×15cm, and the weight 2000g. The pathological finding was a lipoma like type well-defferentiated lipo saroma.
