Figure 3

(a) Low power histopathology view demonstrating one of the circumscribed nodules that comprised the multinodular tumor. Fibroblastic cells are spindled to stellate with variable cellularity set in a collagenous stroma. Slit-like capillaries can be seen as well (center to left). The right side of the image is the surface of the nodule (magnification 10x). (b) Tumor nodules had variable cellularity with hypocellular hyalinized appearing areas (top and left) alternating with regions with higher cellularity (right) (magnification 10x).
