Figure 3
Figure 3 High-grade pleomorphic sarcoma show large pleomorphic tumor cells in a fibrous stroma with numerous mitotic figures (A), tumor cells show a strong diffuse cytoplasmic immunoreactivity to vimentin (B). Other immunoreactions failed to discern any line of differentiation. The “vimentin only” immunophenotype leads to a diagnosis of undifferentiated pleomorphic sarcoma.
