What term is used to describe malignant tumors of fat tissue?

Liposarcomas are the correct term for malignant tumors that originate in fat tissue. These tumors arise from lipoblasts, which are the cells that create fat within the body. Liposarcomas can develop in various locations but are most commonly found in the retroperitoneum and limbs. Given their malignant nature, they are characterized by uncontrolled growth and the potential to metastasize, which distinguishes them from benign tumors.

Adipomas refers to benign tumors of fat tissue, which do not exhibit the same aggressive behavior as liposarcomas. Myxomas are soft tissue tumors typically arising in the heart or soft tissue, but they do not originate from fat tissue. Similarly, neuromas are tumors that affect nerve tissue rather than fat. Thus, the defining characteristics and origin of liposarcomas affirm their classification as malignant tumors of fat tissue.
