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]
