Abstract
Gastric carcinoma with lymphoid stroma (GCLS) is classified as a special type of gastric cancer because of its characteristic features in histology and more favorable prognosis than usual gastric cancers. We report our experience with a case of GCLS presented with ball valve syndrome (BVS). The case involved a man in his fifties complaining of vomiting and epigastralgia. Following abdominal CT scan, impaction of a gastric tumor in the duodenum was diagnosed. The impaction was released endoscopically. A biopsy resulted in moderately differentiated tubular adenocarcinoma. Preoperative EUS showed that the tumor was localized in the submucosal layer, and laparoscopic-assisted distal gastrectomy was performed. Pathological studies of the permanent preparation revealed remarkable lymphocytic infiltration and GCLS was diagnosed.
Grossly GCLSs often present as type IIc or type IIa + IIc in early stages and as type 2 or 3 in advanced stages. This case which was of type 1 and presented with BVS is considered to be rare.
