腹膜后神经内分泌肿瘤误诊为巨大肝癌临床病理分析
Clinical and Pathological Analysis of Retroperitoneal Neuroendocrine Tumor Misdiagnosed as Giant Liver Cancer

目的：分析腹膜后巨大神经内分泌肿瘤(NET-G1)临床病理特点及临床诊治经过。患者男49岁，1年前因体检发现腹部巨大包块，门诊CT示：肝右叶巨块型肿瘤性病变(多为肝CA)，曾行剖腹探查因肿块巨大广泛粘连而放弃治疗，后经过多家医院多位专家会诊，考虑为巨大肝癌。近来自觉乏力、腰痛加重1月余入院。结果：患者行腹膜后肿瘤联合右半肝切除术，术后病理诊断为神经内分泌肿瘤(NET-G1)。结论：影像学检查诊断腹腔巨大肝癌，考虑为腹腔巨大肝癌伴粘连严重要充分鉴别诊断，要结合临床病史、年龄以及病理学检查，诊断思路要开阔、诊断与鉴别诊断必须充分。不能明确诊断一定要先取材活检，避免误诊误治。
Objective: Analysis of the clinicopathological features and clinical diagnosis and treatment of giant retroperitoneal neuroendocrine tumor (NET-G1) in vitro. The patient was a 49-year-old male with a large abdominal mass found by physical examination 1 year ago. Outpatient CT showed that there was a large tumor lesion in the right lobe of the liver (mostly hepatic cancer). Laparotomy was performed to detect the massive and extensive adhesion of the mass and the treatment was abandoned, after a number of hospitals after a number of experts consultation, considering for a large liver cancer. Result: The patient underwent retroperitoneal tumor combined with right hemihepatectomy, and the postoperative pathological diagnosis was neuroendocrine tumor (NET-g1). Conclusion: In the diagnosis of large abdominal liver cancer by imaging examination, it is necessary to fully differentiate and diagnose the large abdominal liver cancer with serious adhesion. It is necessary to combine the clinical history, age and pathological examination. The diagnostic thinking should be broadened and the diagnosis and differential diagnosis should be sufficient. If no definite diagnosis can be made, biopsy must be done first to avoid misdiagnosis and mistreatment.
