Dermatology has become an integral part of medical students’ training, as nearly 10 per cent of all the patients, visiting the general physicians have skin diseases. With advances in the diagnosis and treatment, it has become possible to treat nearly all the skin diseases. Newer therapeutic tools can now treat even the diseases which were considered incurable earlier. In this edition, every chapter has been thoroughly revised and updated with the addition of available information. Some newer methods of diagnosis and treatment have been incorporated while retaining some of the previous material and deleting the outdated ones. Several new photographs have been introduced and a new completely revised appendix has been put in place of ready-reference to various common drugs with their trade names and compositions.
