General information about the body

Morphologic elements of skin rashes

When assessing the affected skin, first of all, the morphology of the rash is established, their prevalence or limitation, localization, symmetry, asymmetry or linearity (for example, along the course of a nerve or vessel), and the features of their mutual arrangement (scattered, grouped, confluent) are analyzed.

Skin assessment

Diagnosis of diseases of the skin and its appendages, as well as various cosmetic defects, is based on the study of the anamnesis, a thorough examination of the skin and visible mucous membranes, and, if indicated, on the results of additional clinical, instrumental and laboratory studies.

Peculiarities of skin barrier properties

The barrier properties of the skin, which determine the body's protection from the effects of external factors, are provided by the complex interaction of the stratum corneum, highly specialized lipids of the stratum corneum, and the water-lipid mantle.

Anatomo-physiological features of the skin and its appendages

The epidermis is a multilayered flat keratinizing epithelium of the epidermal type. The bulk of the cells are keratinocytes (epidermocytes), and there are also dendritic cells (melanocytes, Langerhans cells, Merkel cells). The epidermis consists of the following layers: basal, spinous, granular, shiny, and horny.
