Disease at a Glance

Summary
Granuloma annulare (GA) is skin disorder that most often causes a rash with red bumps (erythematous papules) arranged in a circle or ring pattern (annular). GA is not contagious and is not cancerous. The rash may be localized or generalized. Localized GA is the most common form of GA (75% of the cases) and usually affects the forearms, hands, or feet. The generalized form of GA (15% of cases) presents with numerous erythematous papules that form larger, slightly raised patches (plaques) anywhere on the body, including the palms of hands and soles of feet. The plaques may or may not be in the ring pattern and can vary in color. Less common forms of GA include subcutaneous, perforating, and patch variants. The underlying cause of GA is unknown, but there are several factors that may trigger the disorder, including injury to the skin, viral infections, and certain medications and medical diseases. However, most cases of GA develop in healthy people. Diagnosis of GA is made by the appearance of skin lesions and lack of other physical findings or symptoms. GA may be confirmed by a biopsy and tests may be performed to rule out other associated diseases.

How Can Patient Organizations Help?

Patient organizations can help patients and families connect. They build public awareness of the disease and are a driving force behind research to improve patients' lives. They may offer online and in-person resources to help people live well with their disease. Many collaborate with medical experts and researchers.

Services of patient organizations differ, but may include:

  • Ways to connect to others and share personal stories
  • Easy-to-read information
  • Up-to-date treatment and research information
  • Patient registries
  • Lists of specialists or specialty centers
  • Financial aid and travel resources

Please note: GARD provides organizations for informational purposes only and not as an endorsement of their services. Please contact an organization directly if you have questions about the information or resources it provides.

View GARD's criteria for including patient organizations, which can be found under the FAQs on our About page. Request an update or to have your organization added to GARD

Participating in Clinical Studies

Clinical studies are part of clinical research and play an important role in medical advances, including for rare diseases. Through clinical studies, researchers may ultimately uncover better ways to treat, prevent, diagnose, and understand human diseases.

What Are Clinical Studies?

  1. Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments.
  2. Observational studies involve recording changes over time among a specific group of people in their natural settings.
Learn more about clinical trials from this U.S. Food & Drug Administration webpage.

What Are Clinical Studies?

Clinical studies are medical research involving people as participants. There are two main types of clinical studies:
  1. Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments.
  2. Observational studies involve recording changes over time among a specific group of people in their natural settings.
Learn more about clinical trials from this U.S. Food & Drug Administration webpage.

Why Participate in Clinical Studies?

People participate in clinical trials for many reasons. People with a disease may participate to receive the newest possible treatment and additional care from clinical study staff as well as to help others living with the same or similar disease. Healthy volunteers may participate to help others and to contribute to moving science forward.

To find the right clinical study we recommend you consult your doctors, other trusted medical professionals, and patient organizations. Additionally, you can use ClinicalTrials.gov to search for clinical studies by disease, terms, or location.
