[Current idea of the morphogenetic features of liposarcomas]

The paper considers the current aspects of the morphology, immunohistochemistry, molecular biology of liposarcomas. Particular attention is given to the embryogenesis of liposarcomas and to problems in the immunohistochemical diagnosis of these neoplasms. There is evidence that TLS-CHOP is involved in the PNA processing of liposarcoma cells. Prospects for the diagnosis and treatment of malignant mesenchymal tumors are discussed.
