Minute gastric carcinoid tumor with regional lymph node metastasis.

A minute carcinoid tumor of the stomach developed into a regional metastasis around the celiac axis. There was marked lymphangitic and venous invasion of the tumor cell cluster around the tumor, in the submucosal layer. We wish to emphasize that radical gastrectomy with extended lymphadenectomy should be performed, even for a minute carcinoid tumor, as there will probably be a lymph vessel-related metastasis.
