PPrreelliimmss..iinndddd 55 77//2288//22001111 66::4400::2277 PPMM “This page intentionally left blank" Preface to the Fourth Edition About the book … The importance of Dermatology cannot ever be overemphasized. A quarter of a general practitioner’s patients are ‘dermatological’, and it is necessary for the physician to be well-versed with the presenta- tions of common skin diseases. It is equally important to remember that the skin manifestation may be a clue to the patient’s internal disease. The book is nothing but a simplified and brief journey through skin diseases, peppered with numerous clinical pictures, illustrations, and tables—the basic aim being to familiarize medical students and general practitioners with the plethora of common skin conditions they are likely to encounter and to help them in handling these correctly and not to succumb to the morbid temptation of prescribing steroids— often thought to be ‘panacea of all skin ills’. About this edition … “A picture is worth a thousand words” is an apt description for Dermatology, because it is a visual spe- cialty. So it is necessary for any dermatology textbook to be more of an atlas rather than just full of text. And that is the reason that about 100 new pictures have been added in this new edition.

(cid:2) My mother, who believed that education is the only true wealth and one is never too old to learn. (cid:2) Anil, my better half (!) who has always been a mountain (literally!) of support. (cid:2) My mother-in-law, who believes (wrongly though!) that I am a perfectionist. (cid:2) My sister Sunita, for always believing in my ability. (cid:2) My bacchas, Chandni and Abhishek who have accepted the book as another sib, and are now showing signs of intense sibling rivalry!!
