A 58-year-old Japanese man visited a local clinic for the evaluation of a stomachache. He was diagnosed with intestinal obstruction. His medical history included a proctocolectomy at the age of 38 years, due to familial adenomatous polyposis (FAP). He was referred to our institution, where he underwent a computed tomography examination and endoscopy of the small intestine. The pathological diagnosis was adenocarcinoma. No invasive or metastatic lesions were observed. Therefore, partial resection of the ileum with lymphadenectomy and reconstruction of the ileostomy were performed. Pathological examination revealed that the tumor was type 2, pT3 (SS) , pN1, pPM0, pDM0, pRM0, INFb, ly1, v1, pEX0, PN0. Twenty-nine days after the surgery, the patient was diagnosed with lung metastasis and he underwent lung radiofrequency ablation. We suggest that long-term follow-up is necessary for patients after surgery for FAP, because of the risk of malignant disease developing in other organs.
