It is uncommon in childhood and the peak incidence is between 30 and 50 years. The lesion resembles to the bark of a tree. Figure It is common in atopic dermatitis but may also be secondary to other dermatoses. The term lichen simplex chronicus is used when there is no known predisposing skin disorder.
Prurigo nodularis 43 Secondary lichenification may complicate various pruritic dermatoses. Scaling is often profuse and psoriasiform. Secondary bacterial infection frequently occurs. Ankles and lower leg may also be affected. Other areas of the scalp are less often affected and present as an area of scaling with twisted.

Clinical Features Figure In recent years the management of inflammatory skin conditions has become both more effective and less demanding for the patient.
Major advances in treatment include more effective and safer phototherapy and the use of immunosuppressive drugs that enable inflammatory dermatoses to be managed without the need to attend for dressings or admission to hospital. This is just as well, since dermatology inpatient beds are no longer available in many hospitals. As a consequence, more dermatology patients are managed in the community with a greater role for the community nurse and general practitioner or family doctor.
Dermatology liaison nurses play a very important part in making sure that the patients are using their treatment effectively at home and in maintaining the link between the hospital department, the home situation, and the general practitioner. Self-help groups are a valuable resource of support for patients, and there is now much more information available to the public on the recognition and management of skin disease.
Progress has been made in increasing the awareness of the general public and the politicians who control the resources for health care of the importance of skin diseases. In countries with minimal medical services there are immense challenges— particularly the need for training medical workers in the community who can recognise and treat the most important conditions. This has a major impact on the suffering and disability from skin diseases.
All the chapters have been revised for this new edition and a number of new illustrations included. In addition, there is a chapter on dermatology in general practice.
Colleagues with special areas of expertise have been generous in giving advice and suggestions for this edition, which I trust will be a means of introducing the reader to a fascinating clinical discipline, covering all age groups and relevant to all areas of medicine.
