Three patients with B cell lymphoma diagnosed by endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of pancreatic lesions

Abstract

Three patients with pancreatic lymphoma were seen. Primary pancreatic lymphoma accounts for less than 2% of extranodal malignant lymphomas and less than 0.5% of malignant tumors of the pancreas. In patients with pancreatic lymphoma, an accurate diagnosis is crucial because the tumor is difficult to distinguish from other pancreatic tumors-especially pancreatic cancer-based on imaging findings alone, and because the treatment depends on the specific type of lymphoma. Two of these patients improved after chemoradiation therapy. EUS-FNA was useful for determining the type of lymphoma and determining the treatment strategy.
