Cryoablation for liver metastasis from solid pseudopapillary tumor of the pancreas: A case report

Figure 1 Pathology of solid pseudo-papillary tumor of the pancreas with liver metastasis. A: The tumor is less heterogeneous, the cytoplasm is eosinophilic, and the tumor cells are arranged in a pseudo-nipple around the blood vessels; B: Positive cytoplasmic staining for CD10 (×200); C: Positive cytoplasmic staining for CD56 (×200).

Figure 2 Computed tomography of the liver. A: Before cryoablation, abdominal computed tomography found multiple nodules in the right lobe of the liver; B-F: Follow-up computed tomography scans at 1 year (B), 2 years (C), 3 years (D), 4 years (E), and 5 years (F).
