  • Abstract
  • Look Inside

 The macroscopic classification (Fig. 1) and the qualitative diagnosis of superficial colorectal epithelial neoplasms (typeⅡ) were evaluated in 85 cases (52 cases of carcinoma, 33 cases of adenoma). Most type Ⅱ colorectal carcinomas were of the superficial depressed type (Ⅱc). On the contrary, typeⅡ colorectal adenoma showed both type Ⅱc and type Ⅱa (flat elevated) in equal incidence. Most (70%) type Ⅱc lesions showed marginal elevation surrounding the depression (type Ⅱc+ME). This marginal elevation consisted of reactive hyperplastic glands.

 There were some discrepancies between endoscopic and microscopic classification of the lesions (Fig. 4). The smaller the lesion, the more easily the shape was affected by pneumatic distention at endoscopy and by stretching at fixation (Fig. 3). Thus, the discrepancies between macroscopic and microscopic findings were common in the case of minute lesions. It was thought to be unnecessary to classify minute lesions by subtype. It would be sufficient to describe them as type Ⅱ carcinoma or type Ⅱ adenoma.

 Magnifying endoscopic pictures showed mucosa with reactive hyperplastic glands with a large, regular round pit-pattern, revealed adenoma to have an irregular big tubular pit-pattern, and identified cancer as having irregular big loss of pit-pattern (Fig. 9).
