Subsequent computed tomography showed a hypodense poorly demarcated tumor of the pancreas in the tail-body with impression of infiltrative growth (Fig. 1A). The tumor nuclei were not atypical and the cytoplasm was granular and eosinophilic (Fig. 1B). These cell clusters stained positive for S-100 and CD68 in the cell cytoplasm (Fig. 1C).
