What is a chin lump?
A chin lump is a protuberance or localized area of swelling that can occur anywhere on the chin. Other terms used to describe the various types of chin lumps include bump, nodule, contusion, tumor and cyst. Lumps can be caused by many conditions, including infections, inflammation, tumors or trauma. Depending on the cause, lumps may be single or multiple, soft or firm, painful or painless. They may grow rapidly or they may stay the same size.
Chin lumps due to local infections may appear as boils or abscesses. Many types of infections cause the lymph nodes to enlarge and feel like lumps, most commonly in the neck near the jawbone. Traumatic causes of lumps range from bug bites to severe injuries that can produce a localized collection of blood in the tissues (hematoma).
Both benign and malignant tumors of the skin, soft tissues, or organs can sometimes feel like lumps. In these cases, either a biopsy or surgical removal of the lump can determine whether cancer is present. Skin cysts, which are fluid-filled, sac-like structures that can form in various parts of the body, often feel like lumps. Cysts can also develop in the jawbone and these are firm, nontender, and slowly enlarging. Some cysts may be present at birth, while others develop as a result of inflammation or tumors.
Lumps caused by infection, inflammation or trauma are usually temporary and subside as the underlying condition resolves. Lumps that persist or continue to grow over time may signal more serious conditions such as tumors. A lump on the chin that is associated with head trauma may be accompanied by bleeding in the brain or another emergency and may have life-threatening complications. Seek immediate medical care (call 911) if you, or someone you are with, have a lump on the chin as a result of a head injury.
If you have any lump that is persistent or causes you concern, seek prompt medical care.
