Overview

Classification

Liposarcoma is one type of soft tissue sarcomas, which accounts for about 20% of the mesenchymal malignancies. Liposarcomas may be classified into different types, according to their histologic, cytogenetic, biologic and molecular features. The WHO has proposed the following classification of liposarcomas:[1][2]

  • Well-diferentiated liposarcoma:
  • Adipocytic or lipoma-like
  • Inflammatory
  • Sclerosing
  • Dedifferentiated liposarcoma
  • Myxoid liposarcoma
  • Round cell liposarcoma
  • Pleiomorphic liposarcoma
