The metastatic site of liposarcoma is difficult to determine, and it can metastasize to any part of the body, commonly to the lungs, liver, and bones.
Liposarcoma is a malignant tumor of mesenchymal tissue, which is more common in adults and less common in adolescents. It often occurs in the deep soft tissues, retroperitoneum and other parts of the body, and less frequently in the subcutaneous fat layer. The types of sarcoma include highly differentiated liposarcoma, mucinous/round cell liposarcoma, pleomorphic liposarcoma, and dedifferentiated liposarcoma.
The tumors tend to be nodular or lobulated, and may also be mucinous or fish-like. Under the microscope, sarcoma cells have various morphologies, characterized by the appearance of lipoblasts, the cytoplasm can be seen in the number of different sizes of lipid vacuoles, which can squeeze the cell nucleus, forming pressure marks.
Liposarcoma often metastasizes through blood or lymph, and can involve many organs, the most commonly involved are lungs and liver, and can also metastasize to bone, brain, kidney and other parts of the body.
Liposarcoma patients should consult the doctor in time after diagnosis and follow the doctor’s instructions for treatment.
