Doctors spend much of their time staring at body parts. Specialists spend an even higher percentage of their time staring at the body part that is their particular area of expertise. So, I guess it should come as no surprise that they like to tell each other about the crazy-looking examples they find. And how do doctors tell each other things? By publishing a paper, of course! Some of our favorites include a tumor that looked like the Easter bunny, and an endoscopy result that resembled a jack-o-lantern. Here's one where a patient's aortic valve (the valve the prevents blood from flowing back into the heart once pumped out) looked like a four-leaf clover, instead of the Mercedes-Benz emblem it should have (note the helpful figure from the paper).
