Core Tip

Core tip: Liposarcoma is one of the most common adult soft tissue sarcomas, accounting for approximately 20% of all mesenchymal malignancies. Atypical lipomatous tumor (ALT) is the most common intra-abdominal primary sarcomas. On the other hand, it is an extremely rare malignant adipose mesenchymal tumor. We report the first case of ALT occurring in the ligamentum teres of liver.
