Merkel cell Polyomavirus:

Merkel cell carcinoma is nasty. I had no idea a virus was involved.
I’ve had it and continually look out for a recurrence. It’s like nothing’s there one day, the next day...a pimple...a few days later a good sized wart...quarter to three-eights inch tall soon. Itchy and painful. My dermatologists/plastic surgeon cuts it out. Had several...chest, arm, leg. The doc tells me, when I hit ten, he’ll give me 25% off a facelift. He gave me a punch card. LOL.
