This is a 10 year study of scleroderma patients with calcinosis 1) to better understand how common and if there are any risk factors for having calcinosis

2) to identify common complications associated with scleroderma-related calcinosis.

.

This is a prospective study of scleroderma- spectrum patients focused on soft tissue calcinosis in order 1) to better understand the risk factors (including clinical/laboratory characteristics, and serology) of calcinosis in the scleroderma-spectrum disorders (limited or diffuse systemic sclerosis with or without overlap of inflammatory arthritis and/or myositis).

2) view common complications associated with calcinosis.

Better understanding of scleroderma calcinosis would lead to other studies that eventually will define better treatment options for this incurable and often disabling complication.

Inclusion Criteria:

• Adult scleroderma subjects with and without calcinosis

Exclusion Criteria:

• Subjects unwilling to participate

Adult scleroderma subjects with and without calcinosis will be enrolled
