A Case of Obstructive Jaundice as the Initial Manifestation of Non-Hodgkin's Lymphoma

We report a case of obstructive jaundice as the initial manifestation of malignant lymphoma. The patient was a 39-year-old woman, who visited our hospital because of epigastralgia and jaundice noted since February 2003. Diagnostic imaging revealed a 40 mm stenosis in the lower bile duct, but biliary biopsy showed no malignancy. FDG-PET revealed accumulation in the left breast, left axillary lymph nodes, stomach, lower bile duct, etc., and a diagnosis of malignant lymphoma was made based on cytodiagnosis of the breast mass and biopsy of axillary lymph nodes. CHOP therapy resulted in improvement of biliary stenosis and remission of lymphoma.
