Abstract
Although submucosal cyst of the stomach is a rare condition, the high incidence of the association of this lesion with gastric cancer is widely recognized. We herein report 3 cases of submucosal cyst associated with multifocal gastric cancer (Table 1). Case 1, a 57-year-old male : multiple submucosal cysts, linear ulcer scar, and type IIb cancer (m) in the upper body of the stomach in addition to type IIc cancer (m) at the angulus (Figure 3). Case 2, a 75-year-old male : multiple submucosal cysts, type IIc cancer (m) and type IIc+III cancer (sm) in the lower body of the stomach (Figure 7). Case 3, a 77-year-old female : a submucosal cyst in the body, advanced cancer (pm) in the posterior antrum, type ha cancer (m) in the anterior antrum and atypical epithelium (group III) at the angulus of the stomach (Figure 11). With regard to the relation between gastric submucosal cyst and cancer, we discussed on the pathogenesis of submucosal cyst and frequency of this lesion complicated with gastric carcinoma.
