Ganglion Cyst Quick Overview. A ganglion cyst is a tumor or swelling (benign, not cancerous) usually on top of a joint or the covering of a tendon (tissue that connects muscle to bone). It looks like a sac of liquid (cyst) located just under the skin. Inside the cyst is a thick, sticky, clear, colorless, jellylike material.
Ganglion cysts are very common lumps within the hand and wrist that occur adjacent to joints or tendons. The most common locations are the top of the wrist (see Figure 1), the palm side of the wrist, the base of the finger on the palm side, and the top of the end joint of the finger (see Figure 2).
