A 43-year-old woman went to the ED after several episodes of fainting over the past two days. She had recently had pneumonia and was just finishing up a prescription for erythromycin, so she worried that maybe she was still sick even though her pneumonia symptoms had been clearing up.

What our customers say:

"The wound's appearance reminded me of an image I had seen on a previous VisualDx quiz so I pulled out the application. I typed the most specific aspect of the wound I could think of: pathergy. The second result on the list popped out to me: pyoderma gangrenosum. Reading the description, I realized this may well be [my patient's] diagnosis."

"These quizzes are important to our readers because while some rheumatic conditions are known to be associated with skin manifestations, it is not as well known that cardiology and endocrinology conditions can sometimes manifest as skin conditions."
