Considerations There are many causes of lumps in the neck.
The most frequently seen lumps or swellings are enlarged lymph nodes , which can be caused by bacterial or viral infections, malignancy , and other rare causes. Lumps in the muscles of the neck, almost always in the front of the neck and involving the sternocleidomastoid muscle , result from injury or torticollis . Lumps in the skin or just below the skin are often caused by cysts such as sebaceous cysts . The thyroid gland may also produce a lump, multiple lumps, or swelling in the neck as a result of thyroid disease or malignancy.
