I have replaced the entire article. However, I'd like someone else to look over it, which is why I put an expert tag on the article instead of a cleanup tag. --Mdwyer 04:53, 27 January 2007 (UTC)

It's incorrect to say that a lesion occurs most frequently in regions a, b and c, especially without justification. A puncture wound can occur anywhere. A tumour can occur in a much larger range of tissues than are listed. — Preceding unsigned comment added by (talk) 16:25, 15 April 2012 (UTC)

I don't mean to be rude, but I hope someone is looking at this. As someone who is curious about lesions and doesn't know anything about them, this article confused me a lot. The syntax is off in a major and ambiguous way and it seems like key details are missing. Many of the examples seem to be exclusive to brains without saying "brain lesion". Just totally confusing. I hope someone can clarify the article. — Preceding unsigned comment added by (talk) 14:19, 28 June 2012 (UTC)

I also think this page is confusing. I have removed the History section and the non-cited references that were added at the same time. I would also be tempted to remove the other sections that are specific to brain lesions.Young trotsky (talk) 18:17, 23 September 2014 (UTC)


isn't "lesion" just a fancy name for "damage"?? What difference does it make to say "He has a lesion in Brodmann area 12." instead of "He has a damaged Brodmann area 12."-- ExpImptalkcon 22:10, 5 December 2006 (UTC)

I think it makes sense to say that your first sentence is equal to "He has damage in Brodmann area 12," but I think your second sentence says something slightly different. Damage causes a lesion, and a lesion is also evidence of past damage. But I think the problem is that you can have damage without having a lesion. A puncture wound isn't really abnormal tissue, so it isn't a lesion, but it is still damage. --Mdwyer 04:53, 27 January 2007 (UTC)
Basically, yes it is just a fancy name for "damage." From Taber's Encyclopedic Medical Dictionary: "1. A circumscribed area of pathologically altered tissue. 2. An injury or wound. 3. A single infected patch in a skin disease." Etymologically, it comes from the Latin laesio meaning "wound." I think the sine qua non for a lesion is that it must be visible damage -- either grossly or microscopically. For instance, a DNA mutation causing disease wouldn't be considered a lesion since it's not visible by conventional techniques. —Brim 16:16, 27 January 2007 (UTC)
Well, by that definition, I'm wrong about a puncture not being a lesion. That's why I've got the need an expert tag up there. Brim, from what you know and have read, do you think the expert flag can be removed? --Mdwyer 16:56, 27 January 2007 (UTC)
Your rewrite looks good. As for a puncture wound being a lesion or not... keep in mind that lesion is a loosely-defined word and it's often thrown around without much thought to it. I doubt that most medical professionals would call a puncture wound a lesion, since it's just a little bit too fancy of a term for something as mundane as a puncture wound, but technically I guess it fits. I think it's safe to remove the expert tag. —Brim 17:27, 27 January 2007 (UTC)


The "History" section of this page is so confusing and badly written that I propose that it should be removed entirely. It makes no sense! Katiekillick (talk) 15:13, 7 July 2012 (UTC)
