A retrospective morphological stuffy was conducted on 1677 Iymph nodes which were
removed surgically under the diagnosis of gastric carcinoma, breast carcinoma, colonic
carcinoma, chronic gastric ulcer, and superficial Iymph nodes under the diagnosis of
reactive follicular hyperplasia at Chosun University Hospital during a period of 5 years
from 1980 to 1984.
The hematoxylin and eosin stained sections were examined to evaluate for any
vascular changes. In selected cases further levels were prepared from the paraffin blocks
for Gomori's reticulin stain.
The vascular abnormalities were divided into 3 groups, such as hemangiomatoid,
pan-nodal vasodilatation and miscellaneous types._ The miscellaneous type included the
proliferation of smooth muscle which encircled numerous small hilar arteries and veins.
The results obtained were as follows :
1) The hemangiomatoid lesions were localized lesions which appeared to be associated
with local malignancy, but infrequent in incidence.
2) A more frequent vascular abnormality was pan-nodal vasodilatation, which tend to
affect many nodes in a mingle group and is relatively associated with chronic gastric
ulcer.
3) Miscellaneous lesion was nonspecific and appeared both local malignancy and
chronic inflammation.
4) All three vascular reactions were somewhat more frequent in female than male.
