It’s a shame that Cheron Wicker did not consult with a dermatologist in the beginning [“For seven years, searing pain with no relief,” May 27]. The diagnosis would have been made in a nanosecond. I am a board-certified dermatologist now in my 42nd year of practice. Trauma aside, a bluish or bluish-red, painful, solitary lesion in a distal digit is a glomus tumor until proven otherwise.

I always read Medical Mysteries, but this was the first time I could really identify with it.

I had a glomus tumor removed from my thumb in 1981. Things were different back then: Two nights in the hospital and four months of checkup visits. I had lived with this pain for over 15 years. If I knocked against anything, the pain was intense, but it usually faded after a few minutes so I just put up with it. When I finally decided to do something about it, my regular doctor referred me to a specialist, and he immediately identified the problem.

I can truly sympathize with Ms. Wicker about the pain she endured. But to go through all those surgeries is just beyond understanding!
