@entity9296 and @entity1085 have rarely been reported. An 88-year-old Japanese @entity1 was admitted to our clinic because of hypochondralgia and @entity1087 . Imaging techniques revealed @entity7252 and a multilocular @entity5 in the fundus of the @entity1085 , and cholecystectomy was performed. Grossly, the @entity5 (3.5 x 3 x 3 cm) was multicystic, containing seromucous fluid. The @entity5 was located in the fibromuscular layer and subserosa of the @entity1085 fundus, and protruded into the serosal surface, not into @entity1085 lumen. The mucosa appeared free of @entity5 involvement, and no @entity5990 were recognized. Microscopically, the @entity5 was located in the fibromuscular layer, subserosa and tiny focus of the mucosal surface. The @entity5 consisted of mucin-rich benign columnar cells, @entity6349 mucous cells, malignant papillotubular cells and invasive @entity189 cells. Malignant and atypical @entity5 cells were located in the center of the @entity5 and in the tiny area of the mucosal surface, while benign @entity5 cells were located in the peripheral portions of the @entity5 and in the serosal side. Neither @entity43 -like @entity361 nor an oncocytic change in @entity5 cells was recognized. @entity1086 showed chronic @entity2679 . Immunohistochemically, benign and @entity189 cells were positive for cytokeratins, epithelial membrane antigen, CA19-9, @entity2355 , @entity5089 and @entity21826 , and @entity189 cells were also positive for carcinoembryonic antigen and @entity876 protein. The present case indicates that @entity7157 without @entity361 may occur in the @entity1085 of old @entity1 , and suggests that @entity9296 without @entity361 may transform into @entity1085 .
