Primary duodenal papilla lymphoma producing obstructive jaundice: a case report.

BACKGROUND

Obstructive jaundice caused by primary duodenal lymphoma is a rare disease.

CASE PRESENTATION: We reported a 59-year-old man who underwent endoscopic ultrasonography for obstructive jaundice and found a duodenal papilla tumor. Light microscopy revealed a non-Hodgkin's lymphoma. Immunohistochemical staining showed that the tumor was aggressive B-cell lymphoma. We carried out molecular targeted therapy combined with CHOP regimen chemotherapy.

CONCLUSION

Surgery plays an important role in resolving obstructive jaundice when accurate histological diagnosis cannot be made. After diagnosis, chemotherapy should play a central role in treatment.
