A 79-year-old woman with a rare form of pancreatic carcinoma with massive invasion of the retroperitoneum presented with upper abdominal pain and vomiting. Although examination (computed tomography, barium enema, upper gastrointestinal series) suggested peritonitis carcinomatosa due to pancreatic cancer, a primary lesion of the pancreas was not confirmed by endoscopic retrograde pancreatography. Autopsy ultimately revealed a small tumor (5 x 8 mm) of the uncinate process of the pancreas near the duodenum with peritonitis carcinomatosa. Microscopically, the tumor and its metastasis consisted of poorly differentiated squamous cell carcinoma without adenocarcinomatous change, a rare form of pancreatic tumor.
一名79岁女性，患有罕见的胰腺癌，伴有大量腹膜后侵犯，表现为上腹部疼痛和呕吐。尽管检查（计算机断层扫描、钡灌肠、上消化道造影）提示为胰腺癌导致的癌性腹膜炎，但内镜逆行胰胆管造影未证实胰腺存在原发性病变。尸检最终发现十二指肠附近胰腺钩突有一个小肿瘤（5×8毫米），伴有癌性腹膜炎。显微镜下，肿瘤及其转移灶由低分化鳞状细胞癌组成，无腺癌改变，这是一种罕见的胰腺肿瘤形式。
