Primary Malt Lymphoma of the Common Bile Duct

Abstract

Primary mucosa-associated lymphoid tissue (MALT) lymphoma arising in the common bile duct (CBD) is extremely rare. In our case of MALT lymphoma, CT and MRI showed long, segmental, irregular wall thickening of the CBD and minimal dilatation of the upstream bile duct. A preoperative diagnosis of cholangiocarcinoma was made, but histologic evaluation confirmed MALT lymphoma of the CBD. We herein present a rare case of MALT lymphoma of the CBD with CT and MRI findings.

Primary hepatopancreatobiliary lymphoma: Pathogenesis, diagnosis, and management

“…Its production can also induce expression of BCL-10 and activation of the NF-κB pathway, leading to cell proliferation ( Figure 1 ) ( 27 ). Another possible mechanism is that prolonged chronic inflammation causes irreversible genetic rearrangements, thus disabling the response of cells to IL-2 regulation, eventually helping in the development of MALT lymphoma ( 114 ).…”
