ABSTRACT
The patient was a 55-year-old man who had undergone extended right lobectomy of the liver with a diagnosis of primary hepatic carcinoid tumor. Nine years after the operation, enhanced abdominalCT revealed a tumor measuring 2.2 cm in the remnant liver. He was diagnosed with recurrence of primary hepatic neuroendocrine carcinoma and underwent partial hepatectomy. Pathologically, the tumor cells had round nuclei and formed trabecular patterns. Immunohistologically, the cells were positive for CD56, synaptophysin, and chromogranin A. The Ki-67 index was 6%, which was equivalent to Grade 2 in the WHO classification revised in 2010. Since there were no other lesions suspected to be the primary site other than in the liver, it was diagnosed as recurrence of the primary hepatic neuroendocrine carcinoma. Two years after the operation, he was diagnosed with recurrence of primary hepatic neuroendocrine carcinoma and underwent partialhepatectomy again.
