title: Neuroendocrine tumor presenting like lymphoma: a case report.
abstract: BACKGROUND
  Neuroendocrine tumors are a rare but diverse group of malignancies that arise in a wide range of organ systems, including the mediastinum. Differential diagnosis includes other masses arising in the middle mediastinum such as lymphoma, pericardial, bronchogenic and enteric cysts, metastatic tumors, xanthogranuloma, systemic granuloma, diaphragmatic hernia, meningocele and paravertebral abscess.
  
  
  METHODS
  We present a case of 42-year-old Caucasian man with a neuroendocrine tumor of the middle-posterior mediastinum and liver metastases, which resembled a lymphoma on magnetic resonance imaging.
  
  
  CONCLUSIONS
  The differential diagnosis in patients with mediastinal masses and liver lesions should include neuroendocrine tumor.
