Finding a lump on your hand or finger can be alarming. Fortunately, many hand masses are benign. Two of the most common are ganglion cysts and digital mucous cysts. Although they sound similar, they develop in different locations and have different causes.

Ganglion cysts are fluid-filled sacs that usually develop near joints or tendons. They are most commonly found on the back of the wrist but may also appear on the palm side of the wrist, fingers, or hand.

These cysts contain thick joint fluid that escapes from the nearby joint capsule or tendon sheath. While they are not cancerous, they may fluctuate in size over time. Some become painful, while others simply create a visible lump.

Digital mucous cysts are different. These small cysts usually develop near the last joint of the finger, close to the fingernail. They are commonly associated with arthritis and bone spurs in the distal interphalangeal joint.

Patients often notice a smooth bump that gradually enlarges. In some cases, the cyst presses on the nail matrix, creating grooves or ridges in the fingernail.

Many people wonder if they should pop or drain these cysts at home. The answer is no. Attempting to puncture a cyst can introduce bacteria into the joint or surrounding tissue and increase the risk of infection.

Treatment depends on symptoms. Small painless cysts may simply be observed. Larger cysts that interfere with daily activities, become painful, repeatedly drain, or continue enlarging may require surgical removal.

Dr. Robert Kratschmer, plastic surgeon in Houston, Friendswood, and Pasadena TX carefully removes hand cysts while protecting nearby nerves, tendons, and joints. When treating mucous cysts, addressing the underlying bone spur often reduces the chance of recurrence.

Although these cysts are benign, any new lump on the hand deserves proper evaluation to confirm the diagnosis and rule out less common conditions.

If you have noticed a lump on your hand, wrist, or finger, it is important to have it evaluated rather than trying to diagnose or treat it yourself. While many hand cysts are benign, proper diagnosis helps determine whether observation or treatment is the best option.
