Detailed yet concise, this book uses a comprehensive outline format and is organized in the way that pathology is taught at most medical schools. New to this edition are: the addition of a transplantation chapter, which covers general immunologic mechanisms and pathologic features of transplant rejection, organ-specific transplantation pathology (kidney, liver, heart, lung, bone marrow), graft-versus host disease, and complications of transplantation; K-type questions have been eliminated and replaced by case-based or clinically oriented questions; and a moderate increase in tables and diagrams, to break-up dense outlined text. The NMS outline format provides a logical organization of pathology concepts and eliminates unnecessary words and detail.
