You really don't want this type of tumor. Called a teratoma (latin = monster) this is one scary cancer (or it can be benign) in my opinion. We had to learn about this today in our lecture on neoplasms (neo=new, plasm=growth). It comes from organs that have the potential to create all the different cells types in our body (think: ovary which can differentiate in to the cells necessary for a baby). The picture above includes lots of hair (the black stuff--bottom left), teeth (the white blob--bottom right), skin, brain tissue, cartilage, fat, and a juicy cyst (the yellow stuff, top left).
Boyd wondered the other day if I thought everything in medicine was sad. Because evidently when I'm studying I say "oh how sad" quite often. Well, I told him no, I think some things are gross. Usually that includes things that people do to themselves when they should know better-- like STDs. Since people cannot help getting a teratoma as far as I understand, I think it is sad. But I have to be honest with myself that I think it is really gross too.
