Diagnosing Rheumatic Skin Diseases
Our
experienced dermatologists are experts in evaluating symptoms and diagnosing
rheumatic skin conditions. We begin with a complete evaluation, which includes
a:
- Physical exam
- Review of personal and family
medical history
- Discussion
of symptoms
- Screening
laboratory tests
- Biopsies
of lesional skin (if needed)
Because dermatologists know that there may be a rheumatologic or connective
tissue disease behind certain skin conditions, a referral to a rheumatologist
or other specialist at UT Southwestern may be recommended. This can help with
the early detection and treatment of any underlying disease.
To confirm a diagnosis of a specific rheumatic skin disease, patients
may be tested for the presence of a marker autoantibody (for example, a protein
produced by the immune system). Tests that patients might need include:
- Blood tests: Drawing
of blood to check for specific autoantibodies, show how severe the
condition is, and monitor whether treatment is working
- Skin biopsy: Removal
of a small sample of affected skin to examine under a microscope for signs
of disease
- Direct
immunofluorescence: Removal of a small sample of normal
skin for examination under a special microscope to allow detection of
immune proteins deposited in patient skin
Treating Rheumatic Skin Diseases
The primary treatment for rheumatic skin diseases is corticosteroids
such as prednisone. Additional medications that our doctors might prescribe
include:
- Immunosuppressive drugs, such
as methotrexate, mycophenolate, azathioprine, or cyclophosphamide
- Immunosuppressive,
anti-inflammatory, or immunomodulating biological therapies
- Antibiotic, antifungal, or
antiviral medications to prevent infections
