Small cysts on the body are usually common in the liver, kidneys or inside the extremities and subcutaneous and muscular tissues of the body. If the cysts are relatively small, they are generally benign and do not require special treatment. If they do not affect liver or kidney function and do not have local pain, they can be reviewed regularly. If it suddenly grows larger or causes impaired function and pain, it must be actively treated and can be surgically removed. If it is in the liver or kidney, the cyst can be removed laparoscopically or the fluid inside can be aspirated by puncture to shrink the cyst. If it is a tendon sheath cyst on the surface of the wrist or ankle, the cyst can be ruptured by compression or percussion so that the fluid inside can flow out of the tissue space and be absorbed. For radical excision and removal, surgical incision is necessary to remove the entire cyst envelope to provide radical relief.
