  • Abstract
  • Look Inside

 A 60-year-old woman periodically visited the outpatient clinic in our hospital since one year and six months before the establishment of the present diag nosis. In April 1972 endoscopy of the stomach revealed a map-like reddened area in the upper part of the body on the posterior wall near the lesser curvature. Its oral side was seen to adjoin the transitional zone between the stomach esophagus, while its anterior wall side was not so clear-cut. On the posterior wall side the reddening was prominent in parts, to be distinguished in its margins from the surrounding mucosa. The reddened area contained bleeding spots. Biopsy from this area was twice attempted: cancer was positive in one of seven pieces in the first biopsy and in two of seven in the second. Biopsy specimens from the mid-body and from around the cardia were all negative for malignancy.

 In radiography several very small radiolucencies were noticed in double contrast view almost in the same place as the presumed lesion on the posterior wall of the upper body. As compared with the normal areae gastricae, they were rather rougher, larger and more roundish.

 Gross examination of both the fixed and unfixed specimens completely failed to locate the site of cancer. Histologically, it was adenocarcinoma tubulare, locatized within the mucosal layer and about 3×5 mm in size, located in the upper part of the body on the posterior wall near the lesser curvature. A strip of Ul-IIS about 10 mm long was seen on the lesser curvature adjacent to the cancer lesion.

 Abnormal findings seen in both x-ray and endoscopy are believed to represent these mucosal changes including the minute cancer.
