case_images: Microscopically the tumour was composed of fibroblast-like spindle cells with fascicular and focally storiform arrangement (Figure 4).
case_images: Spindle-shaped tumour cells were positive for CD34 (diaminobenzidine, x400).

case_images: The tumour cells showed strong immunoreactivity for vimentin, weak and focal immunoreactivity for CD34 (Figure 5) and some tumour cells (histiocyte-like) were positive for CD68 (KP 1) (Figure 6).
