Gastrointestinal mucosal biopsies are an active part of the pathologist's day and have increased in the past few years as endoscopic screening has become more commonplace. This new full-color second edition of "Biopsy Interpretation of the Gastrointestinal Tract Mucosa" has been expanded into two concise, comprehensive volumes to offer more complete coverage of both non-neoplastic and neoplastic entities. Like the other books in the "Biopsy Interpretation Series", these volumes are practical references for pathologists to use when making diagnostic decisions based on biopsy specimens. Volume 1 of this second edition focuses on interpretation of non-neoplastic gastrointestinal mucosal biopsies. Coverage is geared to daily practice and includes mucosal biopsies from the esophagus, stomach, small intestine, large intestine, and anus. A companion website will include all of the 300 print illustrations plus an additional 750 e-figures. Volume 2 will focus on neoplastic biopsies and will publish in March 2012.
