Omori et al. reported a case of multiple liver metastases originating from synchronous double cancer of "primary mesenteric neuroendocrine tumor" and rectal cancer. However, the "primary mesenteric neuroendocrine tumor" might be a misrecognition of mesenteric metastasis from ileal neuroendocrine tumor. Ileal neuroendocrine tumor is extremely rare in Japan. Herein, we aim to describe the characteristics of ileal neuroendocrine tumor and mesenteric mass as its common manifestation in reference to their reported case.
大森等人报告了一例源自“原发性肠系膜神经内分泌肿瘤”和直肠癌的同步双癌的多发性肝转移病例。然而,“原发性肠系膜神经内分泌肿瘤”可能是回肠神经内分泌肿瘤肠系膜转移的误诊。回肠神经内分泌肿瘤在日本极为罕见。在此,我们旨在参考他们报告的病例,描述回肠神经内分泌肿瘤及其常见表现——肠系膜肿块的特征。
