Summary
Definition
History and exam
Key diagnostic factors
- Raynaud phenomenon
- digital pits or ulcers
- swelling of the hands and feet
- skin thickening
- loss of function of hands
- sclerodactyly
- heartburn, reflux, and dysphagia
- bloating
- fecal incontinence
- arthralgias and myalgias
- abnormal nail-fold capillaroscopy
- telangiectasia
- subcutaneous calcinosis
- dyspnea
- dry crackles at lung bases
- tendon friction rub
- abrupt onset moderate/marked hypertension
Other diagnostic factors
- fatigue
- dry cough
- decreased exercise tolerance
- weight loss
- inflammatory arthritis
- proximal muscular weakness (inflammatory myositis)
- synovitis
- increased accentuation of the pulmonic component of S2 heart sound
- signs of melena/anemia
Risk factors
- family history of scleroderma
- immune dysregulation (e.g., positive ANA)
- exposure to environmental substances and toxins (e.g., silica dust or solvents)
Diagnostic tests
1st tests to order
- serum autoantibodies
- CBC
- BUN and serum creatinine
- ESR
- CRP
- urine microscopy
- complete pulmonary function tests (spirometry, lung volumes, and diffusing capacity measurement)
- ECG
- echocardiogram
- high-resolution CT scan of chest
- barium swallow
Tests to consider
- chest x-ray
- upper gastrointestinal endoscopy ± biopsy
- serum muscle enzymes
- electromyogram/nerve conduction studies
- muscle biopsy
Treatment algorithm

cardiac tamponade
Raynaud phenomenon: no ulcers
Raynaud phenomenon: with digital ulcer development
generalized skin involvement
GI involvement
myopathy
synovitis, tendon friction rub, or inflammatory arthritis
