A ganglion cyst is a common condition within the hand and wrist. These cysts are noncancerous and appear as a lump or bump underneath the skin. A ganglion cyst is commonly located on the top of the wrist, the palm side of the wrist, the base of the finger, and the top of the finger (near the nail bed).
Symptoms
Ganglion cysts can be categorized by location, size, and pain. They usually surface from the fluid-filled areas on the ligaments or between the bones. These cysts most commonly occur on the wrist or hand.
