The present report describes two cases of Schloffer tumor demonstrating PET false positive. The first case was a 62-year-old female who underwent sigmoidectomy for sigmoid colon cancer. After 8 months, she underwent partial resection of the small intestine for strangulated ileus. Two years after the initial surgery, an abdominal growing nodule demonstrating PET positive was detected. Therefore, she was diagnosed as recurrence of colon cancer, and underwent resection of the previous anastomosis with suspicious recurrent nodule. Pathological examination revealed that the nodule was the suture sinus, the so-called Schloffer tumor. The second case was a 77-year-old female who underwent right hemi-colectomy and cholecystectomy for ascending colon cancer and cholecystlithiasis. After one year, hepatic tumor demonstrating PET positive was detected, so she was diagnosed as liver metastasis, and underwent partial resection of the liver. Pathological examination revealed that the nodule was a foreign body granuloma.
