New Mole, New Problem
If you're on the lookout for suspicious signs of skin cancer, in particular melanoma, new moles may be more problematic than old ones. A team of dermatologists looked at more than 20,000 melanoma cases from dozens of past studies. They found that 71 percent of melanoma diagnoses were related to new moles. The remainder were from existing moles, which tended to be smaller and produced better prognoses.
"We call it the ugly duckling sign," Dr. Darrell Rigel, former president of the American Society for Dermatologic Surgery, told STAT. "If you see a spot that's brand new and growing -- and looks different than its neighbors -- have your dermatologist look at it."

A doctor was giving a lecture to a group of medical students at a teaching hospital.
Pointing to an x-ray, he opined: "As you can see, this patient limps because his right fibula and tibia are radically arched."
The doctor then turned to the class and asked a young man in the front row: "What would you do in a case like this?"
The young man replied, "I suppose I would limp too."

This week in 1997, American biology professor Stanley B. Prusiner won the Nobel Prize for medicine for discovering "prions," described as "an entirely new genre of disease-causing agents."
