Overview

Liposarcoma may be classified into well-differentiated, de-differentiated, myxoid, round cell, or pleomorphic liposarcoma.

Classification

Liposarcoma is a type of soft tissue sarcoma, which accounts for approximately 20% of the mesenchymal malignancies. Liposarcomas may be classified into different subtypes, according to their histologic, cytogenetic, biologic, and molecular features. The World Health Organization proposed the following classification of liposarcomas:[1][2][3]

WHO Classification of Liposarcoma[3]
  • Well-diferentiated liposarcoma:
  • De-differentiated liposarcoma
  • Myxoid-round cell liposarcoma (MRCLS)
  • Pleomorphic liposarcoma
  • Liposarcoma, not otherwise specified
