Histopathological evaluation
Histopathological evaluation showed that the structural tumor mass is capsule, hypocellular, without infiltration, containing scattered fibroblasts (spindle or stellate cells) in the mucoid background. Further evaluation showed the presence of scattered thin collagen fibers, small cells with hyperchromatic nuclei with scanty cytoplasm. The lesion did not have cystic degeneration, mitosis and necrosis (Figure 3).
