Maculopapular

When describing a rash, macules are flat and papules are raised; this seems like an easy enough distinction. Yet whenever I was on medicine or pediatrics, we were often wishy-washy on describing rashes, calling them "maculopapular." After doing two weeks of dermatology, I realize that's a pretty useless descriptor. Hopefully from now on, I'll actually be able to describe rashes better.
