  • Abstract
  • Look Inside

 In this report we classify gastric lymphomas and their related diseases macroscopically into two types, namely group Ⅰ (17 cases) which can be classified as early gastric carcinoma-like lesions, and group Ⅱ (28 cases) which can be classified as advanced carcinoma-like lesions.

 Some obvious differences in clinicopathological findings are observed between the two groups.

 In group Ⅰ, some cases have more than four leasions widely scattered in the stomach.

 The most important requirement for gastric biopsy is to take a large area of material, with as little crushing as possible, from a location enclosing the most representative lesions, but the problem in group Ⅰ is the difficulty in differentiating lymphoma from benign diseases.

 Many cases are of diffuse, large cell type in group Ⅱ; while cases of low grade lymphomas in group Ⅰ are more numerous.

 And many cases of group Ⅰ have m or sm invasion of lymphoma without lymph node metastasis.

 The lesion of group Ⅰ is a “superficial lymphoma”; while that of group Ⅱ is a “classical lymphoma” having a bulky mass with large or small ulceration.

 The problem of whether the two groups are interrelated, or whether they are separate entities is worth further investigation.
