Ganglion Cysts Symptoms, Causes, Diagnosis, and Treatment

What Is a Ganglion Cyst?

A ganglion cyst is a small sac of fluid that appears in a tendon or joint. It generally appears in tissues that connect muscles to bone. The cyst is made up of a sticky, thick, clear, jelly-like material. In some cases, it may appear spongy or firm.

Ganglion cysts are also called bible cysts, and they usually occur behind the hand at the wrist joint. They may also occur on the palmar area of the wrist. Some people experience the disorder in other parts of the body, such as:

  • The base of the fingers on the palm. They usually look like small pea-sized bumps in this area.
  • The top of the foot
  • The outside of the knee and ankle
  • The fingertip, just below the cuticle. They are clinically known as mucous cysts when they appear in this area.

In most cases, a ganglion cyst appears as a misshapen or round lump or bump beneath the skin’s surface. It is commonly seen on your ankle, foot, wrist, or finger. It may also appear clear or translucent because it contains a liquid.
