There are many causes of lumps in the neck. The most frequently seen lumps or swellings are enlarged lymph nodes. These can be caused by bacterial or viral infections, cancer (malignancy), or other rare causes. Enlargement of the salivary glands under the jaw may be caused by infection or cancer. Lumps in the muscles of the neck--almost always in the front of the neck--are caused by injury or torticollis. Lumps in the skin or just below the skin are often caused by cysts, including sebaceous cysts.
All neck lumps in children and adults should be checked immediately. In children, most neck lumps are caused by treatable infections. However, treatment should start quickly to prevent complications or the spread of infection.

An ear lump is a protuberance or localized area of swelling that can occur anywhere on the ear. Other terms used to describe the various types of lumps include bump, nodule, tumor and cyst. Lumps can be caused by any number of conditions, including infections, inflammation, tumors or trauma. Depending on the cause, ear lumps may be single or multiple, soft or firm, painful or painless. They may grow rapidly or may not change in size.
Common sites for ear lumps include your ear canal, ear lobe, and behind your ear. Ear lumps can be caused by exostoses and osteomas, which are types of tumors that grow in the bones of the ear canal. An ear lump and tenderness in the bone behind your ear, along with pain and swelling, could indicate mastoiditis (infection of the mastoid bone).
See your health care provider as soon as possible (primary care doctor), for consultation.
