Overview
Liposarcoma must be differentiated from other diseases that cause a painless, growing mass such as spindle cell lipoma, neurofibroma, dermatofibrosarcoma protuberans, and malignant peripheral nerve sheath tumor.
Differential diagnosis
Differential diagnosis of liposarcoma includes nonadipocytic lesions such as:[1]
- Inflammatory myofibroblastic tumor
- Castleman’s disease
- Spindle cell lipoma
- Neurofibroma
- Dermatofibrosarcoma protuberans
- Malignant peripheral nerve sheath tumor
| Disease | Description |
|---|---|
| Spindle cell lipoma | Composed of bland, sometimes palisading, CD34-positive spindle cells, ad- mixed with eosinophilic refractile collagen bundles |
| Neurofibroma | Characterized by a less cellular S-100– positive spindle cell proliferation with wavy nuclei |
| Dermatofibrosarcoma protuberans | Cytologically bland, monomorphic CD34-positive spindle cell proliferation organized in a distinctive storiform growth pattern and characterized by tendency to infiltrate the surrounding fat in a peculiar ‘‘honeycomb’’ pattern |
| Malignant peripheral nerve sheath tumor | Generally highly cellular tumors composed of tapering or wavy spindle cells featuring perivascular accentuation and focal S-100– positive immunoreactivity in approximately 50% of cases[1] |
