  • Abstract
  • Look Inside

 In the diagnosis of gastric cancer one of the most important factors is whether or not we are able to determine the vertical changes with the mucosal surface as their border, or the degree of unevenness of the mucosal surface, and horizontal changes on the mucosal surface, or the spread of cancer. Early cancer with no changes of the former is Ⅱb, and slight changes in the latter is microcarcinoma. Both are hard to diagnose by X-ray. Diagnosis of microcarcinoma of Ⅱb type would remain most difficult. Most of relatively extended Ⅱb hitherto reported show some, even if slight, unevenness of the mucosal surface. Therefore, diagnosis of minute Ⅱc or Ⅱa type is a good match for that of extended Ⅱb type in its difiiculty. Even in microcarcinoma of Ⅱe type less than 5mm indiameter some have changes in the surrounding area and some have none at all. Ⅱc type microcarcinomas being detected or correctly diagnosed by us are only those that belong to the former. The case here presented is their typical one. A small lesion, measuring 0.4×0.5cm, located on the posterior wall of the gastric antrum, was found in a man aged 40. Macroscopically it was not distinct in the excised speciman, but in and biopsy examinations slight, non-cancerous elevation was recognized around the minute cancer. Such a finding is typical for microcarcinoma of this size. Correct diagnosis was obtained by moderate compression in X-ray study. Taking advantage of such non-cancerous changes can facilitate the detection on diagnosis of minute carcinoma. Obstacles in diagnosis sometimes depend on the location of cancer.

 At all events, clues to the diagnosis of incipient carcinoma should cover not only horizontal diameters of cancer but also three dimentional consideration in diagnosis.
