  • Abstract
  • Look Inside

 A 71-year-old man was admitted to our hospital for a health check using colonoscopy. Barium enema disclosed a small oval flat elevation on the descending colon. The frontal view showed converging folds towards the oval elevation, and the lateral view showed angled deformity. Colonoscopy showed a disc-like elevation with central depression. The resected specimen contained a round flat elevation with converging folds, 8 × 8 mm in size. Histological examination disclosed a well-differentiated tubular adenocarcinoma, slightly invading the muscularis propria layer. No lymph node metastasis was detected. From an analysis of seven cases less than 10 mm in size with invasion of the muscularis propria layer, it was shown that for the differential diagnosis between sm cancer and mp cancer, it is necessary to study the converging fold toward the small flat elevation and the mobility of small lesion by biopsy-forceps.
