An 88-year-old @entity1 , with a history of resection of @entity5 in 1998, was referred to our hospital in August 2010 complaining of upper @entity490 , @entity391 , and dark brown stools. After endoscopic examination, she was admitted with a diagnosis of @entity11247 . Vomiting ecurred when food intake was resumed after fasting. @entity1321 was suspected on abdominal radiography, and @entity1744 was confirmed by contrast-enhanced imaging after placement of an ileus tube. A small @entity4056 with intussusception was detected by computed tomography. At laparotomy, there was no ascites. Intussusception was found due to an @entity5 located approximately 50 cm from the ileocecal valve, and we performed partial small bowel resection. The resected small intestine contained a @entity5 approximately 40 mm in diameter that had penetrated the bowel wall to reach the serosa. Pathological examination revealed a @entity5 that showed poor continuity with the surrounding mucosa, while the histology was @entity957 . Immunohistochemistry showed that the @entity5 was @entity5822 positive, @entity2225 negative, @entity10922 negative, and @entity7434 positive. Based on these findings, we made a diagnosis of small intestinal metastasis at 12 years after radical resection of @entity957 of the lung.
