However, it accounts for less than 1% of all human cancer types. In addition, primary MFH of the pancreas is very rare. Herein, we report of a 37-year-old man who presented with a pancreatic mass and did not show any specific symptoms. Pre-contrast computed tomography(CT) showed a heterogeneous, liquid-filled necrotic mass in the uncinate lobe of the pancreas. Contrast-enhanced CT showed a mild enhancement of solid components and the pancreaticoduodenal artery across the mass. The patient underwent a pancreaticoduodenectomy, ethanol ablation of the liver lesions, and chemotherapy with 4 cycles of ifosfamide and doxorubicin. The tumor recurred in the liver, but not in the pancreas, after 8 months.展开更多

Most of the levels are lower than 400 ug/L. Following biopsies of lung and liver neoplasms, one patient with a clinical diagnosis of lung cancer plus liver metastasis was pathologically diagnosed having an adenocarcinoma. His serum AFP value was 100-300 times the normal value. In order to further explore the clinical significance of an elevation of the AFP level in patients with lung adenocarcinoma plus liver metastasis, and to precisely distinguish a simple liver metastasis from lung adenocarcinoma or from lung hepatoid adenocarcinoma （HAC）, a clinical analysis of the patient, and a literature review was conducted.展开更多
