A 61-year-old man presented with a 3-week history of intractable diarrhea and a 20-lb (9-kg) weight loss. Abdominal computed tomography findings demonstrated a mass in the body of the pancreas and a few hepatic nodules. Results of fine-needle aspiration biopsy of the hepatic lesions revealed clusters of uniform polygonal cells with scant cytoplasm. The cells showed positive reaction to neuron-specific enolase and chromogranin consistent with a metastatic neuroendocrine tumor. Subsequently, the patient underwent irradiation and chemotherapy.
