case_images: Van Gieson staining showed foci of collagen [Figure 6a]. Small to large blood vessels were also seen [Figure 6b]. Marker study showed diffuse and strong positivity for CD34 and Bcl2 and negativity for smooth muscle actin (SMA) [Figure 6c], pan-cytokeratin, S100, and epithelial membrane antigen (EMA) [Figure 6d].
