This book fills the niche to provide basic information to an undergraduate in a nutshell. The text provides all the basic information the student will ever need to know. Key words are shown in bold words so that the student can rapidly go through the book on the previous day or just before the examination. Most students are fundamentally visually-oriented which encourages us to provide many illustrations. This is can serve as a source of rapid review of pathology for even postgraduates in pathology. Numerous illustrations, gross photographs, photomicrographs, tables, text boxes, flowcharts, and x-rays have been incorporated for easy understanding of the subject.
