Osteosarcomatous Divergence in Dedifferentiated Liposarcoma Presenting as a Colonic Mass

Case Reports in Pathology, 2019
Dedifferentiated liposarcomas most commonly arise in the retroperitoneum, accounting for 10% of liposarcomas. Heterologous differentiation occurs in 5-10% of dedifferentiated liposarcomas; however, divergent osteosarcomatous differentiation is rare.

p53 Mutations and Tumor Progression in Well-differentiated Liposarcoma and Dermatofibrosarcoma Protuberans

, 1995
Mutations of the tumor suppressor gene p53 have been identified in a wide variety of human tumors, including soft tissue sarcomas. Most missense mutations of p53 increase the half-life of the protein resulting in its accumulation in the nucleus ...
