This seems to be a slightly shortened version of an earlier article by the same author. The swiss weekly magazine "Das Magazin" published a german translation of this longer version in 2019 [1]. It is an absolutely fascinating read.
Since the article from OP is relatively short on images, the following are links to more images from the german article, with captions translated into english. Warning: images contain depictions of the medical condition discussed in the article. YMMV, but i don't consider them 'gross' or NSFW.
