Dermatology (Skin and Venereal Diseases) is the branch of science concerned with the structure, functions, and diseases of the skin and its attachments (hair, nails, sweat glands). Sub-specialties include venereology (diseases transmitted through sexual intercourse), photodermatology, dermatopathology, dermatological surgery, pediatric dermatology, and cosmetic dermatology.
The skin (and mucous membranes) are human’s first line of defense against both physical (accidents, burns, and traumas) and biological (bacterial or fungal illnesses) infections from the outside environment. Cells that produce melanin pigment and give our skin its color and block harmful sun rays, cells that produce keratin and provide nail and hair production and provide resistance to physical effects by covering the whole skin, and sweat and fat bases that play an important role in the elimination of toxins in our body are found in our skin. It is now known that the skin and subcutaneous tissues include a biological defensive layer made up of immune cells that help prevent infections.
In addition, skin cancers (usually caused by ultraviolet radiation from the sun) are the most common cancers. Although a high rate of cure can be obtained with early diagnosis and treatment in skin tumors, malignant melanoma is the fastest and fatal malignancy among them. In addition, benign skin tumors may require treatment by causing bleeding, appearance disorder, and functional loss.
Cosmetic interventions (eg, botox injections, electrocautery, cryotherapy), including laser beams, should not be performed by health personnel who are not specialized in this field, except dermatology physicians.
