Etymology

Origin of dermatology

First recorded in 1810–20; dermato- + -logy

Explanation

If you have a terrible, itchy rash or troublesome acne, you need to see a doctor who specializes in dermatology, the branch of medicine that focuses on skin diseases and disorders. At the heart of dermatology is the Greek root dermat-, "skin." The -logy suffix, meaning "the study of," or "science," is used for many medical specialties, from oncology (the treatment of cancer) to cardiology (the treatment of heart disease). The practice of dermatology includes cosmetic procedures as well as life-saving procedures including the removal and diagnosis of skin cancers.
