When a painful lump is found on the wrist, it is important to have it examined by a healthcare professional. If the lump is caused by a tumor, surgery may be needed.
However, most wrist nodule lumps are benign. For instance, a carpal boss, also called a carpometacarpal boss, is an overgrowth of bone that typically occurs on the back of the hand. 손목결절종
The carpal boss is usually firm and can cause a mild pain. It is often associated with repetitive activities and can weaken the bone. In some cases, it can be triggered by a tendon thickening to prevent it from catching.
Ganglion cysts are noncancerous swellings that are fluid-filled. These cysts are common on the wrist and can affect a person’s range of motion. They may be caused by a joint deformity, arthritis or other mechanical changes. A large cyst in the joint can result in loss of function.
In other cases, a bump or other mass on the wrist can indicate a serious medical problem. Some causes of wrist lumps are tumors, including giant cell tumors and nerve sheath tumors. An x-ray or ultrasound may be used to determine whether the mass is a tumor or not.
Ganglion cysts are noncancerous lumps that usually form on the wrist.
They are fluid-filled sacs that are filled with a clear jellylike material. Ganglions may appear suddenly and change in size over time. Without treatment, the cysts may go away. However, they may develop into larger masses that cause pain and weakness.
Surgery is usually necessary if the lump is more than two inches in diameter or is located on the bottom of the wrist. This type of lump is more difficult to remove. During the procedure, the surgeon will first remove the cyst from the base. He or she will then remove the cyst along with the joint capsule.
Another form of a lump on the wrist is an epidermal inclusion cyst. It is a collection of keratin, a yellow waxy substance. After a cut or puncture, the cyst forms. As a result, the skin and tissue that surround the cyst become affected. While these types of cysts are painful, they are not cancerous.
Depending on the size and location of the lump, your doctor may prescribe medication. However, most patients don’t have any problems with their cysts. 손목수술
A needle biopsy may be recommended to confirm the wrist nodule diagnosis.
The pathologist will analyze the tumor and decide on the appropriate treatment. Before the procedure, the healthcare professional will review the patient’s medical history and perform a physical examination. X-rays and ultrasounds may be used to evaluate the bones and soft tissue surrounding the growth.
Other types of lumps on the wrist include fibromas and neuromas. They are also benign. Most fibromas and neuromas are not painful, but may cause a popping sensation when pressed. Occasionally, a mass on the wrist may be caused by a disease, such as Rheumatoid Arthritis (RA) or Dupuytren’s Contracture.
