A rare presentation of hepatocellular carcinoma in non-cirrhotic liver

Synchronous Hepatocellular Carcinoma in a Patient with Primary Gastric Cancer: An Exceptional Association

Hepatocellular carcinoma (HCC) is the most frequent type of liver cancer. Liver cirrhosis of any etiology is considered the main risk factor for the development of HCC. However, HCC in noncirrhotic livers remains an uncommon finding. The association of HCC with a primary gastric adenocarcinoma was described in the literature as part of a hepatoid adenocarcinoma which is a special type of primary gastric carcinoma characterized by histologic similarities to HCC with excessive production of α-fetoprotein. Herein, we report the case of a 50-year-old male patient, with no history of pre-existing liver disease, who was admitted due to epigastric pain and vomiting. He was diagnosed with HCC in noncirrhotic liver associated with primary gastric adenocarcinoma. To our knowledge, this is the first case report of synchronous HCC and gastric cancer with no hepatoid adenocarcinoma features in Tunisia.

Non-Cirrhotic Liver is Associated with Poor Prognosis of Hepatocellular Carcinoma: A Literature Review

Primary hepatocellular carcinoma (HCC) is the fifth most frequently reported malignancy, and it is also the second most common cause of cancer-related deaths worldwide. Although most HCC cases have been reported to develop from cirrhosis, accumulating data suggest that HCC is also closely related to non-cirrhotic chronic liver disease. Traditionally, HCC was thought to develop mostly from cirrhosis; however, an increasing number of reports have found that HCC can develop directly from inflammation without cirrhosis. The incidence of HCC in non-cirrhotic liver (HCC-NCL) is high, especially in developed countries. Studies have found that the most common cause of HCC-NCL is neglected fatty liver disease. This type of HCC has unique clinical characteristics and is closely related to metabolic disorders. Unfortunately, the prevention of HCC-NCL has not received enough attention worldwide, and there is also a lack of specific screening methods and clinical guidelines. This article mainly reviews the etiology, incidence, clinical characteristics, and screening markers of HCC-NCL to improve the understanding and prevention of this disease.
