The emphasis of your quotes is misleading imo:-
Point 1
[/i]
Erythema is a medical term for burn. That is not at odds with stungun marks - which are burns. It is also well known that if a stungun is used with force, then the prongs themselves will cause additional injury in the form of abrasions.
An abrasion occurs when the skin surface is broken.
Point 2 - your emphasis
Point 2 - I think this should be the emphasis

Again - perfectly feasible for a stungun to abrade the skin as it is for handcuffs to do so.
Meyer, who peformed Jonbenet's autopsy did not describe anything as a burn.
The point is that marks left by a stun gun have been described as abrasions. Meyer didn't say "burn" nor did these other people. They all said "abrasion."
While erythema can describe burns, its use is not limited to burns. I suppose one can make that argument that all skin irritations are burns but I dont think most people, including doctors use the word burn so universally.

Erythema
Definition
* Erythema is abnormal redness and inflammation of the skin caused by the congestion and dilation (widening) of the capillaries (tiny blood vessels). The effect is usually localized or patchy. In layman's terms, erythema is a skin rash.
Some references include the mucous membranes as well as the skin in their definition.
Additional Information
Rashes have many different causes such as heat, drugs, ultraviolet rays, ionizing radiation, over-exposure to sunlight and/or allergic reactions.
The term "erythema" is often used in conjunction with other words or modifiers to indicate a very specific type of rash. For example, erythema multiforme refers to a skin rash that results from an allergic reaction.

Recombinant human interleukin 1 beta (IL-1 beta), given intraperitoneally to mice as a single injection, significantly suppressed the development of arachidonic acid (AA)-induced ear oedema. This effect was noted 2 h after administration and for at least 5 days afterwards. IL-1 beta was effective in the dose range of 250 ng-20 micrograms/mouse. Injection of IL-1 beta per se resulted in erythema of the ears, and thus, IL-1 beta has the capacity not only to induce and augment but also to suppress inflammatory responses. Indomethacin administered as subcutaneously-implanted pellets did not influence the
IL-1 beta induced-ear erythema, but suppressed to some extent the effect of IL-1 beta on the AA-induced ear oedema.
