Abstract
Liposarcoma is one of the most common malignant soft tissue tumors, although it rarely occurs in the chest wall. A 58-year-old man was referred to our hospital for further evaluation of an abnormal shadow identified on a chest computed tomography (CT) scan in a medical examination. CT scan revealed a 3-cm, ill-defined mass with a low density in the left posterior chest wall. Magnetic resonance imaging confirmed a high signal intensity mass in the T1-weighted sequence. A bright part in the tumor on fat- suppressed images still existed. Surgical resection of the tumor including the seventh and eighth ribs with an approximately 3-cm margin was performed with a diagnosis of suspected primary liposarcoma of the chest wall. Histopathological examination showed the tumor to be a well-differentiated liposarcoma. Because the recurrence site of liposarcoma is usually local, wide resection of the primary lesion with an adequate surgical margin is essential for successful management.
