“…The histological types were frequently reported as mucosa-associated lymphoid tissue (MALT) lymphoma [ 9 , 10 ], DLBCL [ 7 , 11 ], IVLBCL [ 6 , 12 ] and follicular lymphoma [ 13 , 14 ], and there were rare cases with the coexistence of DLBCL and MALT lymphoma [ 15 ], and malignant lymphoma and gallbladder adenocarcinoma [ 16 ]. We compare the clinical features of reported cases of gallbladder MALT lymphoma (n = 13) and gallbladder DLBCL (n = 15) in Table 2 to evaluate the difference in characteristics between the two subtypes, which are considered to be common in gastrointestinal malignant lymphoma, including the stomach.…”
