Overview
Laboratory Findings
Biopsy
Although imaging assists in the diagnosis of liposarcoma, a biopsy is needed to confirm the disease and determine the histopathological subtype of liposarcoma.
Subtype | Findings |
---|---|
Atypical Lipomatous Neoplasm (ALN)/Well-Differentiated Liposarcoma (WDL) | Multivacuolated adipose cells and spindle cells with a hyperchromatic nuclei. Fibrotic areas and atypical stroma cells. |
Dedifferentiated Liposarcoma | Transition from a low-grade to a high-grade differentiation within the same mass of well-differentiated liposarcoma. |
Myxoid Liposarcoma | Multinodular mass with round cells, hyaluronic acid matrix. High cellularity at the periphery and low cellularity inside the mass. |
Pleomorphic Liposarcoma | Lipoblasts with increased size, hyperchromatic nuclei, acidophilic cytoplasm and eosinophilic hyaline globules. |
