This book, Illustrated Textbook of Dermatology, deals with various skin disorders. With the advances made in the field of dermatology during the last few decades, it has become possible to treat and possibly cure several diseases which till recently were considered to be incurable. This has led to a large number of patients seeking dermatologic advice and this figure is expected to go up in future because a dermatologic patient not only expects his/her disease to be controlled but also to get rid of the marks and scars left behind by the disease process. Over the years, the dermatologists have developed several techniques to achieve these objectives too. An attempt has been made to classify the diseases according to their chief aetiological mechanism, and the old system of classification based on morphological features has been discarded. The treatment methods described in the book are those, which are currently employed for the treatment of these diseases.
