Mallory bodyOne or more aggregates of randomly oriented paranuclear eosinophilic microfilaments (which stain for cytokeratin, p62 and ubiquitin). While Mallory bodies are classically seen in alcoholic liver disease, especially if centrizonal, but may also occur in alcoholic steatohepatitis (ASH), non-alcoholic steatohepatitis (NASH), primary biliary cirrhosis, primary sclerosing hepatitis, hepatitis C, Wilson’s disease, abetalipoproteinaemia, Indian childhood cirrhosis, intestinal bypass surgery for morbid obesity, corticosteroid therapy, amiodarone therapy, Weber-Christian disease, perhexiline maleate hepatitis, diethylaminoethoxyhexestrol-induced hepatitis, fatty liver in obesity, diabetes, idiopathic fatty liver, postintestinal resection, radiation pneumonitis, asbestosis, and idiopathic cirrhosis. They may also be seen in neoplasia: hepatocellular carcinoma, macro regenerative nodules, focal nodular hyperplasia and dysplastic nodules.
