Dermatology (from the Greek derma, skin) is the branch of medicine that deals with the skin and connected tissues (hair and hair, nails, sweat glands, etc.).

Dermatologists are doctors who specialize in the diagnosis and treatment of diseases and cancers of the skin and its appendages. The skin is the largest organ in the body and at the same time the most visible.

Although some dermatological diseases only affect the skin, many others are the manifestation of a systemic disorder, that is, affecting different tissues or organs of the body.

Consequently, the training of the dermatologist must include: rheumatology; immunology; neurology, infectious disease and endocrinology.

It has been ascertained that there are correlations between skin pathologies (acne, alopecia, psoriasis, dermatitis, etc.) with emotional aspects and / or conditions of stress (Psychodermatology).
