NCI Definition: An atypical lipomatous tumor/well differentiated liposarcoma that shows progression to a usually non-lipomatous, high grade sarcoma. The non-lipomatous sarcoma component may be present in the primary lesion or at the site of recurrence. [1]

Dedifferentiated liposarcomas most frequently harbor alterations in MDM2, CDK4, GLI1, TNFAIP3, and LATS1 [2].

Most Commonly Altered Genes in Dedifferentiated Liposarcoma

MDM2 Amplification, CDK4 Amplification, GLI1 Amplification, TNFAIP3 Amplification, and LATS1 Amplification are the most common alterations in dedifferentiated liposarcoma [2].
