What is Rheumatology – Dermatology Clinic?

Rheumatology – Dermatology clinic is a multidisciplinary collaboration between Dermatology and Rheumatology to provide comprehensive care to patients with complex medical conditions such as:

  • Dermatomyositis
  • Lupus
  • Scleroderma
  • Eosinophilic Fasciitis
  • Morphea
  • Psoriasis and Psoriatic Arthritis
  • Pyoderma Gangrenosum
  • Necrobiosis Lipoidica 
  • Inflammatory conditions such as SAPHO, PAPA syndromes


Disease Pathogenesis:

Autoimmune connective tissue diseases result from a complex interplay between genetics, the immune system, and the environment.



Symptoms of autoimmune connective tissue diseases are highly variable and heterogeneous. They can include arthritis, muscle pains, tightening of the skin, and can even involve organs such as the lungs, kidneys, and heart.  



Diagnosis is made collaboratively between Dermatology and Rheumatology using patient history, physical exam findings, and laboratory results. Skin biopsy is often helpful in making the diagnosis.

Treatment of autoimmune connective disease is multifactorial and is aimed at:

  • controlling inflammation;
  • monitoring for systemic involvement;
  • enhancing function and mobility; and
  • improving the quality of life

We often use immunosuppressive and immunomodulatory therapies,  such as cyototoxic drugs, biologics, and IvIg.

Because the best course of treatment is unique to each individual patient, the multi-specialty team at UC Davis will discuss the best options with you.
