Pleomorphic liposarcoma of the chest wall: A case report

Abstract

Liposarcomas represent the most common type of soft tissue sarcoma. Liposarcoma is sub-classified into dedifferentiated, myxoid, pleomorphic, and unspecified types, with the pleomorphic form being the most rare. The most common locations of this tumor are the popliteal fossa, retroperitoneum, neck and genitourinary system. Primary axillary, chest wall and intrathoracic origin of this lesion is extremely rare with few studies available to guide treatment. This study describes the wide surgical excision of a pleomorphic liposarcoma of the chest wall, which was successfully resected after obtaining magnetic resonance imaging, computed tomographic angiogram, and positron emission tomography scan. We also describe how the definitive diagnosis was established by histopathologic analysis.
