Gastric carcinoma with lymphoid stroma. Its morphologic characteristics and prognostic correlations.

A type of gastric carcinoma was specified under the designation carcinoma with lymphoid stroma. Grossly, this carcinoma was characterized by clear circumscription, usually with a central ulceration. A histologic feature distinguishing this carcinoma was the presence of a nondesmoplastic stroma infiltrated uniformly with an abundance of lymphocytes and plasma cells throughout the entire area of the tumor. Sparse population of less pleomorphic cancer cell nests of thin trabecular, microalveolar, or primitive tubular pattern widely separated by the intervening stroma was another feature peculiar to this tumor. Carcinoma of this type was found in 4% of a total of 1041 cases of gastric carcinoma removed surgically. A high survival rate was noted among the patients undergoing surgery for this carcinoma. A proposal was made on the separate classification of this tumor from common gastric carcinomas.

[Case report: Aneurysm of the Rt-vertebral artery which terminates as the Rt-posterior inferior cerebellar artery (author's transl].

A case aneurysm of the Rt-vertebral artery which terminates as the Rt-posterior inferior cerebellar artery is reported. It belongs to rare anomalies that one of two vertebral arteries terminates as the posterior inferior cerebellar artery of the same side, though various anomalies arise very often in a vertebral artery system. Such an anomaly had been recognized in approximately 0.2% among vertebral angiographies. We had experienced 4 such anomalous cases among 501 vertebral angiographies which had been performed in our neurosurgery clinic from the beginning of 1967 to the end of June of 1973. A case among them had an aneurysm at a distal portion, the other one had a tumor. The process of the origin of such an anomaly is briefly discussed.
