78-year-old male was diagnosed with Metastatic well differentiated neuroendocrine carcinoma in liver. There is an undefined finding in the cecum that might be the primary tumor, and hepatic metastases that can be surgically respected. The imaging tests support the assumption that the primary tumor is in the small intestine.

78-year-old male was diagnosed with metastatic well differentiated neuroendocrine carcinoma with unknown primary. He recently underwent explorative laparotomy that revealed solitary metastasis in the liver, and a hard lesion in the mid-ileum suspicious for the primary carcinoid. A frozen section showed foreign body type giant cell granuloma. Left lateral segmentectomy of the liver showed a white hard lesion. The expert recommends a regular follow-up that should consist of abdominal ultrasonography combined with CT or MRI.
