52-year-old male was diagnosed in 2004 with a carcinoma of the lower rectum and underwent surgical anterior resection of the rectal tumor which was a well differentiated adenocarcinoma. In 2008 he underwent emergency operation for a perforated pyloric ulcer and then a radical resection of a gastric tumor which infiltrated the entire thickness of the gastric wall. It was a G3 diffuse type adenocarcinoma with signet ring cells, at pT3N2 stage.

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.
