A case of repeat hepatectomy for liver metastasis from solid pseudopapillary neoplasm of the pancreas: a case report

BACKGROUND: Solid pseudopapillary neoplasm of the pancreas is a rare tumor in young women, metastasizing in only 5–15% of cases, and most commonly to the liver. Although treatment guidelines have not been established, surgical resection is usually performed. We report a rare case of repeat hepatectomy for liver metastases after distal pancreatectomy with solid pseudopapillary neoplasm. CASE PRESENTATION: The patient was a 71-year-old woman who underwent distal pancreatectomy for solid pseudopapillary neoplasm, and liver metastasis occurred 4 years after the first surgery. Partial liver resection was performed for four liver metastases, and histopathological examination revealed a diagnosis of liver metastasis from solid pseudopapillary neoplasm. However, 18 months later, liver metastases were detected again; three tumors were identified, and partial resection was performed, which has provided 18 months’ recurrence-free survival. CONCLUSIONS: Long-term prognosis can be expected following R0 resection for resectable liver metastasis from solid pseudopapillary neoplasm.
