case_images: Chest computed tomography scan of an intrapulmonary solitary fibrous tumor, largely occupying the left hemithorax (mediastinal window).

case_images: fig1
case_images: A chest CT scan revealed a large necrotic and heterogeneous mass occupying almost all the left hemithorax (Figure 1).
case_images: Proliferation of spindle or oval cells, arranged in a fascicular fashion with ropey collagen fibres, associated with variably dilated blood vessels often displaying staghorn-like appearance. Mitotic figures were few ((a) x100, (b) x200).

case_images: The neoplastic cells presented a low mitotic activity (2 mitoses per high-power field) without atypia or necrosis (Figure 2).
case_images: The spindle cells show strong and diffuse positivity for (a) CD34 and (b) bcl2; (x200).

case_images: Immunohistochemical staining was positive for CD34, bcl2 (Figure 3), and vimentin (Figure 4) but was negative for cytokeratin, SMA, desmin, and S100.
case_images: The spindle cells show positivity for vimentin (x200).
