NCI Definition: A liposarcoma characterized by the presence of varying proportions of pleomorphic lipoblasts in a background that resembles undifferentiated pleomorphic sarcoma. It is the rarest liposarcoma variant and usually has an aggressive clinical course. [1]

Pleomorphic liposarcomas most frequently harbor alterations in TP53, RB1, ATRX, CYSLTR2, and SMARCA4 [2].

Most Commonly Altered Genes in Pleomorphic Liposarcoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, RB1 Loss, and TP53fs are the most common alterations in pleomorphic liposarcoma [2].
