The World Health Organization's histologic classification of gastrointestinal tumors. A commentary on the second edition

Jeremy R JassH Watanabe


The World Health Organization's (WHO) histologic classification of gastrointestinal tumors has been revised. Although the general basis of classification and the overall outline remain similar to the first edition, advances in the last decade justified changes in classifying certain entities; among them were malignant lymphomas, endocrine tumors, and dysplasias. Several newly recognized entities have also been added.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
