Granuloma Annulare: Symptom, Treatment

Overview

Granuloma annulare is a fairly rare, chronic condition which presents as reddish bumps on the skin arranged in a circle or ring. The bumps are usually on the hands and feet.

The bumps or lesions usually disappear on their own within two years without treatment. It initially occurs at any age and is four times more common in females.

Occasionally, granuloma annulare may be associated with diabetes or thyroid disease when lesions are numerous or widespread. Rarely, it may be related to cancer, especially in older people who doesn’t respond to treatments.


Symptoms

The symptoms can vary, depending on the type of the condition. Generally, it causes reddish bumps in a ring pattern.


Types

The granuloma annulare is usually asymptomatic aside from the visible rash. Depending on different varieties, the signs and symptoms can vary. Common types of granuloma annulare are as follows:

  • Localized

This is the most common type of granuloma annulare. The bump borders present as circular or semicircular, with a diameter up to 5 centimeters, and they present as reddish or skin-colored bumps on the hands, feet, wrists and ankles of young adults.

  • Generalized

Adults will experience this less-commonly type, which trigger reddish or skin-colored bumps on most of the body including the trunk, arms and legs.

  • Patch-type granuloma annulare
  • Under the skin

This type is also called subcutaneous granuloma annulare which affects young children most. It will produce small, firm lumps, instead of a rash on the hands, shins and scalp.

  • Perforating granuloma annulare


Causes

The exact causes for granuloma annulare are not clear. Minor skin injuries and some drugs may trigger this condition. Sometimes it is also caused by:

  • Animal or insect bites
  • Vaccinations
  • Sun exposure
  • Infections such as hepatitis
  • Tuberculin skin tests


Diagnosis

This condition is diagnosed based on the appearance of the affected skin. Sometimes, the doctor may also use a sample of the skin.


Treatments

Generally, granuloma annulare doesn’t need any treatments, but if you are bothered by how your skin looks or how you feel, you can turn to the following treatment options:

  • Corticosteroid Creams or Ointments: Cover the cream with bandages or an adhesive patch. These kinds of products can help improve the appearance of the bumps and help them disappear faster.
  • Corticosteroid Injections: Patients need to take repeated corticosteroid injections until all the symptoms clear up.
  • Freezing: Applying liquid nitrogen to the affected area can help remove the lesions.
  • Oral Medications: Antibiotics, antimalarials or drugs will be prescribed to prevent immune system reactions.
  • Light Therapy: Certain types of light such as lasers may be helpful to treat this condition.
