What is haematoma? How to use in English

The word "haematoma" originates from the classical Greek language. It is a medical term used to describe a collection of blood outside of the blood vessels due to injury, bleeding, or other medical conditions. The term "haematoma" is derived from the Greek words "haima" meaning "blood" and "tome" meaning "swelling" or "pressure." In ancient Greek, physicians used the term "hēmatōma" to describe any type of swelling or collection of blood that was not part of the normal circulatory system. Over time, the term "hemoma" (coined during the 19th century) was sometimes used interchangeably with "haematoma," although it is now considered to be outdated. In modern medical terminology, the term "haematoma" is still used to describe different types of blood collections, such as a subdural haematoma (the accumulation of blood between the dura mater and the brain) or an epidural haematoma (the accumulation of blood between the skull and the dura mater). So, the word "haematoma" has a long and fascinating history, rooted in ancient Greek medical terminology and reflecting the evolution of medical understanding over time.
