Diseases affecting the human skin are common, and are important because the absence of normal skin function, as well as sometimes being life-threatening, can severely impair quality of life. This may be exacerbated by the fact that people with skin disease may suffer the effects of stigma, on occasion stemming from others belief that skin changes are the result of contagious disease. Skin diseases affect all ages and a very huge number of people. Assessment of the skin is valuable in the management of anyone presenting with any medical problem and, conversely, assessment of the other body systems is important when managing primary skin diseases. In this course we will deal with various skin disorders, their pathogenesis, clinical features, investigations, diagnosis and their treatment both conventional and homeopathic.
