Hello @joyful1,

Welcome to Connect. What a lovely username!

In many people, scleroderma harms structures beyond the skin — such as blood vessels, internal organs and the digestive tract. Here is more information from Mayo Clinic:http://www.mayoclinic.org/diseases-conditions/scleroderma/home/ovc-20206014

@mooneagle @dash99999 @sebley12 have talked about scleroderma, and I wonder if they would have some more insight for you.

@joyful1, are you experiencing any symptoms with regard to the mass in your colon? Have you seen a gastroenterologist?
