I don't have it, but was doing some reading and got a bit confused.

Hopefully someone will correct me if I am wrong, but it's my understanding that Mixed Connective Tissue Disease (MCTD) is a separate entity but has symptoms of other connective tissue diseases such as scleroderma. However, I don't think you have to have a diagnosis of scleroderma, for example, in order to have MCTD.
The Mayo Clinic has a patient info article on it that says, in part: "Mixed connective tissue disease (MCTD) is an uncommon autoimmune disorder that causes overlapping features of primarily three connective tissue diseases — lupus, scleroderma and polymyositis. Mixed connective tissue disease also may have features of rheumatoid arthritis. For this reason, mixed connective tissue disease is sometimes referred to as an overlap disease."

That's as I understand it too.
My current 'official' diagnosis is MCTD. A lot of my symptoms are more indicative of Lupus than anything else, but I have the antigen scl70 which is a specific marker for Scleroderma. Until you have reached a specific criteria for each individual auto immune disease, there will be no clinical diagnosis, so it tends to stay as MCTD until (or if) other symptoms develop which meet the required criteria
Hope that makes sense?

The explanation I've just written - according to what I've just read, actually relates to UCTD, but it was the explanation my rheumatologist gave me....... I think....
Oh why is life so difficult?

We also have an explanation of mixed connective tissue disease (MCTD) on our main site.
I hope you find that good reading!
