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) | 4 subtypes: lipoma-like, sclerosing, spindle cell and inflammatory. Multivacuolated lipoblasts and spindle cells with a hyperchromatic nuclei. Fibrotic areas and atypical stroma cells may be observed. |
| Dedifferentiated Liposarcoma | Abrupt 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. Mitotic activity is normal and the nuclei is normochromatic. |
| Pleomorphic Liposarcoma | Pleomorphic lipoblasts with hyperchromatic nuclei, acidophilic cytoplasm and eosinophilic hyaline globules; spinde cells and multinucleated giant cells may be observed. |
| Mixed-type Liposarcoma | Mixed features of myxoid, pleomorphic and well-differentiated liposarcoma. |

Laboratory Tests
- There are no specific laboratory test findings for the diagnosis of liposarcoma.
- In cases of ureter or kidney involvement, an elevated creatinine and BUN may be seen.
- Anemia may be present, specially if there is bleeding associated with the liposarcoma. [3]
