Table 1 Summary of cases of primary mucosa-associated lymphoid tissue lymphoma resembling Klatskin tumor

From: Mucosa-associated lymphoid tissue (MALT) lymphoma as an unusual cause of malignant hilar biliary stricture: a case report with literature review

Case Author, year Age/sex Radiologic findings Surgical findings Treatment
1 Shimura et al. [7] 59/male Irregular, incomplete stenosis from hilum to the lower part of the bile duct Mass (4.5 × 3.5 cm) around the EHD Right trisegmentectomy + caudate lobectomy
2 Shito et al. [9] 71/male Dilatation of IHD with a circumscribed heterogeneous mass in the main hepatic junction Dense, white, nodular mass (5.0 × 2.5 cm) in the main hepatic junction Left hemihepatectomy + caudate lobectomy + radical bile duct resection + Roux-en-Y hepaticojejunostomy + chemotherapy (CHOP, 3 cycles)
3 Yoon et al. [8] 62/male Dilatation of IHD with long, segmental, circumferential wall thickening of entire extrapancreatic portion of CBD + cystic duct + right posterior, anterior segmental IHD + left secondary biliary confluence Diffuse wall thickening of EHD with smooth inner and outer surface without mass lesion Right hemihepatectomy + caudate lobectomy + radical bile duct resection + Roux-en-Y hepaticojejunostomy + chemotherapy (CVP, 6 cycles)
4 MiKail et al. [10] 58/female Dilatation of IHD with a mass at liver hilus with intrahepatic biliary dilatation   4 cycles of R-CHOP (rituximab/cyclophosphamide/doxorubicine/vincristine/prednisolone)
5 This case 86/female Diffuse dilatation of IHD and wall thickening of CHD Intraluminal mass in the proximal CBD and on the duodenal side, a spreading tumor-like lesion Radical bile duct resection + Roux-en-Y hepaticojejunostomy
