Hepatocellular carcinoma (HCC) is the most common primary malignant tumor of the liver in adults. Steatohepatitic HCC (SH-HCC) is a recently described, rarer variant of HCC and is associated with nonalcoholic fatty liver disease (NAFLD). The relationship between fatty liver disease and/or steatohepatitis and SH-HCC is now known. This subtype can be confused with lipid-containing nodules (such as cirrhotic nodules, regenerative nodules, focal nodular hyperplasia) clinically, radiologically and histopathologically. Here, the histopathological features of SH-HCC, its relationship with fatty liver disease and briefly its clinical features will be discussed. In addition, histopathological features of this specific variant, immunohistochemical staining of the tumor and diagnostic difficulties in tru-cut biopsies will also be discussed. Actually, I think this article will raise clinicopathological awareness about this rare variant.
