细针穿刺活检(FNA)所致的针道癌瘤种植很少见,而引起的腹腔内种植则更难于发现。本文报告1例FNA引起的腹腔内神经内分泌类癌的种植。患者男性39岁,因数小时腹痛入院,B超显示胆囊结石,CT发现胰头部有一囊实性肿物直径6cm,在胰十二指肠部位有一致密钙化团块。因诊断不能肯定,于CT引导下行FNA,由肿瘤的前方穿刺2次,取两个部位活体,无併发症?钐逑赴赴庖咦橹旧?细胞角蛋白和上皮细胞膜抗原阳性,波形蛋白和结蛋白阴性,故考虑为癌性而非肉瘤性。MRI和选择性动脉造影显示肿瘤血供丰富,由胃十二指肠动脉供血。两个月后行开腹探查,肿瘤位于十二指肠部位,在靠近胰头处为以前FNA的穿刺处,该处腹膜散布很 Fine needle aspiration biopsy (FNA) is rare for needle cancerous tumors, and intra-abdominal implants are more difficult to find. This article reports one case of FNA-induced implantation of intra-abdominal neuroendocrine carcinoids. The patient was 39 years old. He was admitted to the hospital with abdominal pain of a factor of less than 1 hour. The B-scan showed gallstones. CT revealed a solid cystic mass with a diameter of 6 cm on the head of the pancreas and a dense dense calcified mass in the pancreatic duodenum. Due to the diagnosis can not be affirmed, guided by the CT under the FNA, from the front of the tumor puncture 2 times, take two parts of the living body, no complications? Go to visit the old? Cytokeratin and epithelial cells Positive cell membrane antigens, negative for vimentin and desmin, it is considered cancerous rather than sarcomaous. MRI and selective arteriography showed that the blood supply of the tumor was abundant and was supplied by the gastroduodenal artery. Two months later, laparotomy was performed. The tumor was located in the duodenum and near the head of the pancreas was the puncture site of the previous FNA. The peritoneum was scattered there.
