Dedifferentiated liposarcoma
Dedifferentiated liposarcomas (DDLPS) are malignant adipocytic soft tissue neoplasms that have progressed from primary or recurrent atypical lipomatous tumors/well-differentiated liposarcomas and are characterized by a much higher rate of recurrence, metastasis in about one-fourth of the cases a...
Article
Pleomorphic liposarcoma
Pleomorphic liposarcomas are high-grade malignant neoplasms arising from adipocytic tissues characterized by a variable number of pleomorphic lipoblasts and the absence of areas of well-differentiated liposarcoma and other lines of differentiation.

Article
Myxoid pleomorphic liposarcoma
Myxoid pleomorphic liposarcomas are extremely rare aggressive malignant neoplasms arising from adipocytic tissues characterized by a mixture of pleomorphic and myxoid features and the absence of genetic fusions and amplifications seen in well-differentiated liposarcoma and other lines of differe...

Low-grade fibromyxoid sarcoma
Low-grade fibromyxoid sarcomas also known as Evans tumors are malignant fibroblastic soft tissue neoplasms characterized by alternating fibrous and myxoid elements and a propensity to late recurrence and metastasis.
