About skin and skin diseases
The skin, the largest organ of the human body, has multiple functions.
It enables the communication with the external environment, collects all sensory data, represents a barrier for infectious and chemical agents, participates in the regulation of body temperature, and prevents dehydration. Sweating eliminates waste products from the body.
The skin consists of three layers – the outermost layer – epidermis, the middle layer – dermis and the inner layer – subcutis. Most skin diseases have very apparent characteristics. Variations may exist depending on the conditions in which the disease occurs.
Sometimes it is necessary to allow the disease to develop in order to be sure of the diagnosis (characteristic distribution of changes and their modification over time).
Skin diseases can be divided into inflammatory processes, infectious diseases, autoimmune diseases and skin tumours.
In some patients, the appearance of changes may be atypical. Then it is necessary to do a biopsy, so that the pathologist, together with a dermatologist, could help make a correct diagnosis.
Skin biopsy consists of taking a part of the tissue where the change has occurred.
After taking the sample, the bleeding is stopped by radiofrequency coagulation or by suturing a wound, and the skin sample is sent for pathohistological analysis. In skin tumours, the entire tumour is removed if its size allows it.
If the change is large and the dermatologist is not sure whether it is malignant, a biopsy can be performed, i.e. excision of the most suspicious part of the lesion which is then send for pathohistological confirmation.
When it comes to infectious agents, the bacteria and fungal culture tests are performed.
Viral diseases are very sensitive to environmental conditions.
A sample is taken to test for the presence of viruses that manifest on the skin only when the dermatologist is not sure what it is.
Skin changes can be a marker for underlying internal disease.
