case_images: A brain CT scan showed an expansile bone lesion in the right frontal bone, invading the surrounding soft tissues (Figures 1A, B). Similarly, a chest CT scan showed a heterogeneous mass in the manubrium of the sternum composed of soft tissue and bone components, in favour of metastasis (Figure 1C).

case_images: Histopathological examination revealed fibromuscular tissue infiltrated with round tumour cells with small to moderate amounts of cytoplasm and high mitotic activity accompanied by vascular invasion, which was consistent with a small round cell tumour with sarcomatous pattern (Figure 2A, B).
case_images: A high-magnification (40x) pathology shows round cells with small to moderate amounts of cytoplasm and high mitotic activity accompanied by vascular invasion.
