We report a case of spontaneous regression of gastric carcinoid tumors associated with gastritis type A.
The patient was 48-year old man. Endoscopic examination showed many small protruding lesions on the gastric body. Biopsy diagnosed it as a carcinoid tumors.
His serum gastrin level was remarkably high (≧3000pg/ml) and gastric parietal cell autoantibody was positive.
These findings suggested that the multiple gastric carcinoids in this patient were associated with gastritis type A.
We classified the tumors into Type I according to Rindi's report and considered that these tumors were harmless and that there was no indication for major surgery such as total gastrectomy.
Endoscopically,the carcinoid tumors were shown to be regressed and the level of serum gastrin was decreased during follow-up treatment.
These findings suggest that gastric carcinoid tumors associated with gastritis type A do not need to be removed immediately.
