Abstract
The patient was a 63-year-old woman who had undergone distal pancreatectomy for a solid pseudopapillary neoplasm (SPN) 21 years ago at another hospital. Regular postoperative follow-up was completed with no signs of recurrence, and she was attending our hospital for management of diabetes and hypertension. Twenty-one years after the primary surgery, she complained of anorexia and an abdominal computed tomography scan and magnetic resonance imaging revealed a large mass (> 10 cm) on the left hepatic lobe. Extended left lobectomy was performed for diagnosis and treatment. Pathologically, the liver tumor was similar to the primary SPN specimen and the tumor was positive for vimentin, CD10, CD56, and progesterone receptor. These findings indicated that the tumor was a liver metastasis of SPN. We experienced a very rare case of complete excision of a liver metastasis of an SPN that was resected 21 years ago.
