Description of Case No. 5:
Marked periarticular irregular calcifications are noted around the shoulder. No bony lesion is identified.
Scleroderma (Progressive Systemic Sclerosis)
Scleroderma is also known as systemic sclerosis. It is an autoimmune connective tissue disorder. Scleroderma involves multiple organs.
Soft tissue calcification in scleroderma occurs not only in the digits but also on the face, axilla, forearms, lower legs, and pressure areas such as the ischial tuberosities.
Also, periarticular “tumoral” collections can appear at single or multiple sites and simulate the findings in milk-alkali syndrome, hypervitaminosis D, and renal osteodystrophy.
