I hear a lot of unsolicited disgusting tidbits: I've listened to Y talk about draining abscesses. I've heard accounts of getting hit in the face with placenta, I've heard about every color and texture of discharge you can imagine. I've accidentally touched dried blood spatters on Y's white coat. Hell, I have held a cadaver's testicle. I thought I was unbreakable(for a layperson).
But something has finally grossed me out to the point of gagging: a teratoma. It's, as far as my unscientific brain can understand, a tumor that contains "mature elements" such as teeth or hair. Or, in extremely rare cases, LIMBS.
