exhibits a wide spectrum of histologic features.

Surgical excision is the mainstay in treatment of liposarcoma
, with the objective of wide resection with negative margins.
The value of fat-suppressed T2 or STIR sequences in distinguishing lipoma from well-differentiated liposarcoma
. Eur Radiol.
Upper aerodigestive tract liposarcoma
: Report on four cases and literature review.
It remains unclear what causes liposarcoma
. However, sometimes the tumor is noticed after experiencing an injury.
Mass and pericardium both revealed well differentiated liposarcoma
which was CDK 4 positive and ALK rearrangement was not seen.
Other possible diagnoses like lipoblastoma, lymphangioma, liposarcoma
or lymphangiolipoma should be considered.
represent approximately 20% of all soft tissue sarcomas and are divided into various subtypes including atypical lipomatous tumors/well-differentiated liposarcomas
(ALT/WDLs), de-differentiated liposarcoma
, myxoid liposarcoma
, round cell liposarcomas
, and pleomorphic liposarcomas
For example, with exclusion of fat-containing lesions using MRI, we should be very careful to perform compartment resection for group 2 diseases without liposarcoma
At the same time, the histopathologic examination of the atrial mass showed a high-grade sarcoma consistent with dedifferentiated liposarcoma
. The tissue exhibited spindle cells with pleomorphism, multinucleated giant cells, and inflammatory cells.
Histological examination showed mixed well-differentiated and well-dedifferentiated liposarcoma
in the primary lesion (Figures 3(a), 3(c), and 3(e)).
