Humans with wings or other things?

I need to put together a beginning-to-end case study on a pathology for a radiology class. I'm looking for ideas on what pathology to use. Mesothelioma would be an example of an overused topic. I'd like to do something rare and a bit bizarre, something visually captivating. Like a human who's grown wings, for example. Any suggestions?
Black Hairy Tongue Syndrome certainly is odd enough to suit me. But I don't think x-rays would be involved. The webbed fingers and toes is closer, but still not exactly what I'm looking for. Polydactylism (extra fingers or toes) would be perfect, but I'm pretty sure a couple of my classmates are doing that one. Keep suggestions coming though! Thanks!!
