Preface to the Seventh Edition
G
We acknowledge the support shown by each of our esteemed readers (present and past) for placing the book at the numero uno
position amongst the pathology books for PGMEE. To meet the expectations of students, we have tried to further improve this
seventh edition. R
The book has been fully colored to increase its appeal to the esteemed readers. We have intentionally chosen the topic of
‘Immunology’ because apart from being very important, it is considered as one of the mVost difficult chapters of Pathology.
Dear friends, the apprehension regarding the National Eligibility Cum Entrance Test (NEET) has now been taken care of
as the examination pattern has not been modified drastically. Cracking the NEETd exam and other important PG examinations
require a thorough knowledge and understanding of the subject. Readers of this book have got an edge over others because
of the strong theory and conceptual questions. This along with the key pointes given under the heading of various boxes in the
chapters has helped many of you to get extremely good ranks in NEET 2013, 14 and 2015.
It is a humble request from our side that all the chapters (and not tonly general pathology) of this book has to be read by
the student so as to maximise the benefit. This is because many additiional concepts and questions asked frequently in the exam
n
have been explained in systemic pathology chapters. This is one important point which came as a gist differentiating the people
getting a good rank in NEET versus those who did not.
U
In our constant endeavour to improvise the book, there has been incorporation of important additions in almost all chapters
along with the new section of Most recent questions. The question bank of the every chapter has been subdivided into smaller

portions. It will help students to solve MCQs after reading the theory of a particular topic of a chapter.
-
For getting a grasp on the NEET questions in a better way, a new section in the end comprising of Image Based Questions

has also been added.
9
In this seventh edition, we have added a lot of diagrams and flow charts to make learning interesting and easier. Another
salient feature of this edition is the updating9 of appropriate authentic references from standard textbooks particularly in regard
to the controversial questions so that reader gets all the relevant information under one roof. Other salient features of the
current edition are: r
i
• All references have been uphdated from Robbins 9th edition
• The question bank has been expanded and includes the most recent questions
• More color plates for imaage based questions have been added
• A summary of important information added in Robbins 9th edition has been mentioned separately at the end of each chapter.
t
We have fully revised the book and corrected the typographical and some other errors present in the previous editions.
We have also added plenty of vital information under the heading of ‘Concept’, ‘Info’ and ‘Subject Links’ at multiple places in
almost all the chapters in the book. Further, we have also expanded some of the old topics.
Questions from latest entrance examinations of AIIMS have been added. Several other questions have been incorporated
from PGI, DNB and other state PG entrance examinations. In some topics, there are contradictions between different books. In
such a situation, we have quoted the text from Harrison’s Principles of Internal Medicine, 18th edition.
To help the students to understand the subject better, Dr Gobind has started Ayush Institute of Medical Sciences. Any
query regarding the admission in the same maybe addressed to Dr Gobind at the under mentioned e-mail ID.
We must admit hereby that despite keeping an eagle’s eye for any inaccuracy regarding factual information or typographical
errors, some mistakes must have crept in inadvertently. You are requested to communicate these errors and send your valuable
suggestions for the improvement of this book. Your suggestions, appreciation and criticism are most welcome.

Preface to the First Edition
Pathology is one of the most difficult and at the same time most important subject in various postgraduate entrance examinations.
As we experienced it ourselves, most of the students preparing for postgraduate entrance examinations are in a dilemma,
whether to study antegrade or retrograde. Antegrade study takes a lot of time and due to bulky textbooks, some important
questions are likely to be missed. In a retrograde study, the students are likely to answer the frequently asked MCQs but new
questions are not covered. We have tried to overcome the shortcomings of both of the methods while keeping the advantages
intact.
In this book, we have given a concise and enriched text in each chapter followed by MCQs from various postgraduate
entrance examinations and other important questions likely to come. The text provides the advantage of antegrade study in a
short span of time.
After going through the book, it will be easier for the student to solve the questions of most recent examinations, which are
given at the end of the book.
Eighth edition of Robbins is just to strike the Indian market. We have arranged this edition directly from US and added the
references from its text. Further, important differences between 7th and 8th edition of Robbins have been mentioned with the
relevant questions.
It is very difficult and at times very confusing to remember large number of pathological features. To make learning easy,
several easy to grasp MNEMONICS have been given throughout the text.
Despite our best efforts, some mistakes might have crept in, which we request all our readers to kindly bring to our notice.
Your suggestions, appreciation and criticism are most welcome.
