Dedifferentiated liposarcoma, light micrograph. Liposarcoma is one of the most common sarcomas of adulthood. It arises from fat in deep soft tissues of the extremities and retroperitoneum. The patients are usually in their sixth or seventh decades of life. Histologically, liposarcomas are subdivided into well-differentiated, myxoid and pleomorphic subtypes. This image shows dedifferentiated liposarcoma which arises when a well-differentiated liposarcoma (shown in the upper right of the image resembling a lipoma) progresses to a higher-grade, less well-differentiated neoplasm (seen in the lower left of the image). The higher-grade component usually resembles a fibrosarcoma or an undifferentiated pleomorphic sarcoma. De-differentiation occurs after a latent period of several years. Magnification: x100. | |
