According to Wikipedia:
- "Erysipelas is a relatively common bacterial infection of the superficial layer of the skin."(1)
- "Cellulitis is a bacterial infection involving the inner layers of the skin."(2)
- "Paronychia is an inflammation of the skin around the nail."(3)
I can understand the distinction made between erysipelas and cellulitis. However, I do not get why the term "paronychia" has been introduced. Given the previous definitions, paronychia could have been named "finger erysipelas" or "finger cellulitis". By the way, I am not aware of any other anatomical location where skin infections get such a specific name.
What is, therefore, the motivation of using the term "paronychia" in place of "erysipelas" or "cellulitis" ?
Many thanks in advance.
