I've missed you, and the medical knowledge in your answers! What's the most interesting thing you've learned lately in med school?
Dear Darling Sandwich Vixen,
You are nice! Here's one interesting fact I learned a little bit ago:
Psoriasis is a chronic skin condition that involves red, scaly plaques on the skin. It's usually limited to one or a few areas on any given person (i.e., they'll have psoriatic plaques on both knees for years and years, but nothing elsewhere on their body). However, if someone with psoriasis does something to injure their skin anywhere on their body, that skin will often heal with psoriatic skin, even if there had previously been normal, unaffected skin there. This is called the Koebner phenomenon and one of the classic ways this is seen is if someone scratches their skin or gets a tattoo. Cool, huh?
