Our skin is truly amazing organ, so essential yet so often neglected. Its main function is to protect our internal organs against external environment. Skin weighs about four kilograms and covers an area of two square meters. It consists of three layers:
- Epidermis – the most superficial layer of skin. It has no direct blood supply, therefore dermis nourishes it via diffusion. It contains four cell types: Merkel cells, Langerhans cells, melancolytes and keratinocytes (they are the major component, almost 95% of consists from these cells). Cell division enables self-regeneration of epidermis, it takes four weeks for differentiating cells to move from stratum basale, through stratum spinosum to the stratum corneum, where cells are constantly shed from the surface.
- Dermis – layer of skin between epidermis and subcutaneous tissue. It is composed from collage, elastic fibers and extrafibrillar matrix. Dermis contains superficial and deep plexus vascular networks. They are connected by vertical communicating vessels and their function is to regulate temperature, supply nutrition, modulate inflammation and help out with wound healing.
- Subcutaneous tissue – layer of fat between the dermis and fascia. It has two components: actual fatty layer and deeper vestigial layer of muscle. Adipocyte (fat cell) is the main cellular component of subcutaneous tissue. The main function of this skin layer is to absorb trauma, insulate the body and serve as a reserve energy source.
The spectrum of skin diseases and disorders, also known as dermatoses is immensely broad. There are thousands of skin conditions, however only few of them account for the most visits to the physicians. Classification of these conditions is very challenging. Most textbooks present a classification based on location, morphology, etiology etc.
