This book provides the pathologist with detailed morphologic descriptions and diagnostic guidance in recognizing these mimics as they occur in the gastrointestinal system and liver. In addition, descriptions and diagnostic guidance are provided for the range of lesions that may mimic benign masses but are in fact neoplastic. Throughout the book, comparisons of neoplastic mimics with true neoplasms are provided at clinical, gross, and histologic levels. In the presentation of every entity, the points that contribute to differential diagnosis are emphasized. Hundreds of color images and analysis of diagnostic mimics guide the pathologist through recognizing and distinguishing the usual variants, morphologic anomalies, and misleading features that may easily lead to an inaccurate interpretation and missed diagnosis. Since many of the entities described are uncommon, Neoplastic Mimics in Gastrointestinal and Liver Pathology emphasizes imaging and clinical correlations throughout to support the pathologist as a consultant to the entire diagnostic and clinical management team. Every pathologist who sees gastrointestinal and liver cases will find this book an invaluable working tool to ensure accurate diagnosis.
