Pancreatic Neuroendocrine Tumor with Primary Hepatic B Cell Lymphoma / 대한내과학회지

ABSTRACT

Pancreatic neuroendocrine tumors (NETs) frequently accompany metastatic lesions, and hepatic metastases are the most common of all NETs. However, another disease may also be present, potentially leading to misdiagnosis and metastasis of a NET. Clinicians should consider an active diagnostic evaluation for metastatic lesions, including liver biopsy, particularly when the hepatic lesion has distinct characteristics from the primary tumor. In our case, the patient had both a pancreatic NET and a primary hepatic lymphoma. She underwent laparoscopic distal pancreatectomy with splenectomy, and progress of the primary hepatic lymphoma was observed in the outpatient clinic.
