The patient was a 47-year-old man undergone low anterior resection of the rectum with D3 lymph node dissection for rectal cancer in November 2005. Abdominal CT scan conducted in November 2006 disclosed a tumor 18mm in diameter on the lower abdominal midline surgical wound. FDG-PET revealed accumulations of contrast material in the same area as the CT scan showed and in the vicinity of the intraperitoneal abdominal wall. As for tumor markers, both CEA and CA19-9 were in normal ranges. Metastatic tumors of rectal cancer were suggested and the tumors were removed in December 2006. One of the two tumors was located in the abdominal wall being adjacent to the bladder and other one was enveloped by the greater omentum. The histopathological diagnoses of them were Schloffer tumor and Braun tumor, no malignant cells being demonstrated.In the treatment of tumors at where accumulations of contrast material are seen on FDG-PET, Schloffer tumor and Braun Tumor must be kept in mind as differential diagnoses of metastatic tumors.
