The second edition of this book is devoted entirely to the liver. It is much more comprehensive than the previous edition published 26 years ago, and includes three times as many illustrations as well. as the ""TNM classification of tumours of the liver"". A number of new lessions are described, viz. biliary papillomatosis, the fibrolamellar variant of hepatocellular carcinoma and epithelioid haemangioendothelioma. Several subtypes of hepatoblastoma are mentioned, and a serous type of bile duct cystadenoma is described. The section on adenomatous hyperplasia, including macroregenerative nodules, has been amplified. These revisions update the classification which will continue to facilitate comparison of data by providing a standardized international terminology.
