What is Pencil-in-Cup Sign?

  • by

I’ve written a number of articles on some of the 100 different forms of arthritis. But still, I had never heard of ‘pencil-in-cup’ sign when an editor at WebMD assigned me a piece on it.

That’s probably because it’s a relatively rare complication of a very severe subtype of inflammatory arthritis—typically psoriatic arthritis. 

So I was excited to get this assignment for two reasons. I got paid to learn about a topic that I was unfamiliar with. And it was my first article for WebMD. 

That last part is a big deal, because WebMD has been supplying people with solid information on health and medical topics almost as long as the internet has existed. 

If you’re curious, you can read more about pencil-in-cup sign here.

And if you’re a Canadian who’s looking for arthritis-related information or resources, I highly recommend visiting The Arthritis Society’s website.

My thanks to:

  • Dr. Christopher Morris, a rheumatologist at Arthritis Associates in Kingsport, Tennessee, who very generously agreed to speak with me about pencil-in-cup sign as background for the piece.
  • The American College of Rheumatology, for connecting me with Dr. Morris.
