Show Me the Science with Luke O'Neill · The Science of Psoriasis · 23 Apr 2026 podcast

And lo and behold, it's subtype of psoriasis.

You see loads of neutrophils.

You might call it neutrophilic psoriasis.

And that ends up in pus in these lesions.

And as I'll come back to, there's a slight difference with pustular psoriasis versus plaque psoriasis.

So there's these different types that have been spotted.

They were mainly described, oh, decades ago, I suppose, because you could see the skin was slightly different between people with these different types of psoriasis.

Now, there's one other type as well to mention, and it's called psoriatic arthritis.

Now, that is a really sort of a challenging condition for people because not only do you have psoriasis in your skin, you've also got arthritis, and that means your joints are sore.

Because, of course, arthritis is an immune disease of the joints.

So psoriatic arthritis, you get both.

And that can be very debilitating.

Not only are you getting scaly red patches, but your joints are in agony as well.

And it's slightly different to normal arthritis.

The psoriasis is slightly different as well.

So it's a subtype again.

So in some ways, then, you have four subtypes.

And often in medicine that happens, by the way.

Now, let's say 150 years ago, something like a disease is described, like, say, whatever it might be.

It could be a skin disease.
