Abstract

症例は66歳男性.右季肋部痛,黄疸を主訴に入院となった.精査で総胆管の狭窄,十二指腸乳頭部の腫大,回腸末端のびらん性病変を認めた.生検結果はいずれもMALTリンパ腫であり,回腸病変を併存する総胆管・十二指腸乳頭部MALTリンパ腫と診断した.<i>Helicobacter pylori</i>除菌療法を行い一時的に病変の縮小を認めたが,その後増大傾向となったため化学療法を追加し,病変の縮小・消失を認めた.

We report a rare case of mucosa-associated lymphoid tissue (MALT) lymphoma of the common bile duct and the papilla of Vater. A 66-year-old man was admitted to our hospital with right upper quadrant pain and jaundice. Endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography showed common bile duct stenosis. Further endoscopy revealed swelling of the papilla of Vater, with erosion at the ileal end. The patient was pathologically diagnosed with MALT lymphoma and treated for <i>Helicobacter pylori</i> eradication, after which the lesions improved. However, 1 year later, the lesions began to enlarge again;thus, he was treated with 6 courses of combination chemotherapy (R-CHOP). After treatment, the tumor and erosion of the papilla of Vater disappeared and the stenosis of the common bile duct improved.
