摘要
BACKGROUND Primary hepatic neuroendocrine carcinoma(NEC)is rare,and a combination with hepatocellular carcinoma(HCC)and cholangiocarcinoma(CCA)is extremely rare.To date,only four combination cases have been reported.The present paper describes the fifth patient.CASE SUMMARY A 32-year-old Chinese man with chronic hepatitis B was hospitalized for persistent upper abdominal pain.Abdominal computed tomography(CT)examination revealed a liver mass.The tumor was located in the 7th and 8th segments of the liver,and CT and magnetic resonance imaging findings were consistent with the diagnosis of HCC.Laboratory examinations revealed the following:Alanine aminotransferase,243 U/L;aspartate aminotransferase,167 U/L;alpha-fetoprotein,4519μg/L.Laparoscopic right lobe hepatectomy was performed on the liver mass.Postoperative pathology showed low differentiation HCC plus medium and low differentiation CCA combined with NEC.One month after the surgery,the patient suffered from epigastric pain again.Liver metastasis was detected by CT,and tumor transcatheter arterial chemoembolization was performed.Unfortunately,the liver tumor was progressively increased and enlarged,and after 1 mo,the patient died of liver failure.CONCLUSION This is a rare case,wherein the tumor is highly aggressive,grows rapidly,and metastasizes in a short period.Imaging and laboratory tests can easily misdiagnose or miss such cases;thus,the final diagnosis relies on pathology.
