Usefulness of endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNA) in patients with malignant lymphoma derived from pancreas

Abstract

A female in her 70s was admitted to our hospital because of fever, upper abdominal pain and general fatigue. Transabdominal ultrasonography and CT showed a 90-mm solid tumor in the head of the pancreas and some metastatic liver tumors. The biopsy specimens obtained by EUS-FNA revealed aggregation of atypical lymphocytes. Histologically, the tumor was diagnosed as large B cell lymphoma according to several immunohistochemical stainings. After 3 months of chemotherapy, the primary and metastatic tumors had disappeared showing complete remission. This patient has no recurrence for over 2 years.
