Liposarcoma pleomórfico: estudio molecular de un caso y revisión bibliográfica

Pleomorphic liposarcoma is a high grade sarcoma occurring generally in the sixth to seventh decades of life and mainly affects the deep soft tissue of the lower extremities. As it can show a wide variety of morphologic patterns, it may be confused with other adipocytic and non adipocytic lesions. Definitive identification of pleomorphic lipoblasts is indispensable for diagnosis; however, as they can be very scarce, extensive sampling of the tumor is recommended.
