Soft tissue sarcoma with metastasis to the stomach: A case report

Figure 1 Large left shoulder mass.

Figure 2 Chest computed tomography scan showing mass of left posterior chest (A) and suspected left pulmonary metastasis (B).

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.

Figure 4 Resected left shoulder mass (A), cross section of resected shoulder mass showing central necrosis and smooth glistening dense fish flesh like tumor at the periphery (B).

Figure 5 Endoscopic view of the stomach shows a mass with surface ulceration and blood clots (A), the photomicrograph (B) reveals a malignant neoplasm, composed of densely cellular stroma with spindle cells containing pleomorphic nuclei.
