I hadn't considered that but it's a distinct possibility. She still doesn't have behcets though. As is the suggestion that she forgot herself because she wrote it herself. It's a damned wierd medical report anyway.
Yeah, it isn't proof of anything like you pointed out. What this paper is saying is that neutrophils are depositing on the vessel walls which is a marker of some kinds of vasculitis like Behcets. But also hypersensitivity vasculitis which can be caused by just about anything: antibiotics, bacteria, viruses, blood thinners... most cases have no known cause. Almost all cases resolve in a few weeks just by discontinuing whatever drug/treating whatever bug is causing it. So she might have hit the jackpot and actually developed a mild case of vasculitis just by destroying her body over the years. Or maybe her immune system is just going "fuck fuck fuck fuck!" and doing all sorts of crazy shit because it's constantly fighting off infections trying to set in and trying to heal wounds she keeps intentionally reopening.
And honestly, being limited to her shins isn't even that unusual, as the skin manifestations of vasculitis often are limited to or concentrated in the lower legs. If she weren't a habitual oversharer and totally crazy munchie with a long history of faking sick for attention, I could believe she had real behcets and just picked at the rash it caused until that happened. She's shown videos of her clawing at it, after all, so it's not like she's hiding that she's been peeling off the scabs and interfering with healing. I could easily see behcets + dermatillomania or something causing that kind of extreme damage.
What truly gives away that she doesn't have Behcet's is that she has no other problems. She's healthy as a goddamned ox. An extreme case of vasculitis like she purports to have would not just be limited to the skin. That's just the wikipedia/WebMD version where it mentions skin, genital, and mouth ulcers and nothing else because that's all that's
required for a diagnosis. Doesn't mean it's the only thing that can or would happen. Vasculitis to this degree that is not responding to treatment would almost undoubtedly cause serious organ damage that would lead to a more concrete dx PDQ. They wouldn't still be sending out histo samples going "idk is this behcets?" because she'd be going blind or in kidney failure or coughing up blood and that combined with the lesions would be good enough to diagnose it with a bit more confidence.
Willing to stand corrected, not a medfag just a geek, and there are some vasculitis conditions that are limited to a single organ (for example, there's a known but rare variant of Microscopic Polyangiitis that only affects the kidneys), but I just can't imagine such an extreme case having no other measurable effect on her body whatsoever.
