Skin: Clinical Applications:

The skin is an important part of any physical examination of a patient
In part, this is because it may be examined with the naked eye without the need for any invasive or intrusive procedures
In addition to disorders of the skin itself disorders of other organs in the body may be reflected in changes in the appearance of the skin
As such the skin is an important diagnostic indicator of the general well being, or otherwise, of the individual
For example:

Certain endocrine disorders may result in increased hair growth,
A yellow skin colour may be found with jaundice,
A blue-grey skin colour may be found with some respiratory or circulatory problems,
Characteristic rashes are often associated with infectious diseases eg.chickenpox

The skin appendages, hair, sweat glands, nails are derived from the epidermis and retain continuation with at least the stratum germinativum of the epidermis
In severe abrasions/burns these appendages may assist in the healing process by the capacity of the basal cells (continuous with the proliferative stratum germinativum of the skin) to proliferate and contribute to wound healing
