Peripheral lymphadenopathy without an obvious cause after the history and physical examination presents a diagnostic dilemma.
The location of peripheral lymph node groups is shown schematically in the figures (figure 1 and figure 2). Distinguishing between localized and generalized lymphadenopathy can help to formulate a differential diagnosis. Cervical — The anterior cervical lymph nodes are often enlarged because of one of a variety of infections of the head and neck or to some systemic infections such as infectious mononucleosis caused by Epstein-Barr virus (EBV), cytomegalovirus infection, or toxoplasmosis.

The lump is defined as any protrusion or abnormal enlargement that develops under the skin or above the skin. The growth of the lump can be so large and evident or it can be so small that it can go unnoticed.
Lump on back of neck for most are often caused by minor conditions although in some cases it can be due to something more serious such as the development of cancer.
Tonsillitis is the inflammation of a ball shaped structure located at the back of the throat and is known as tonsil. Lymphoma is one of the serious conditions that can cause the formation of a lump at the back of the neck.
The treatment for the lump on the back of the neck depends on the severity and nature of the lump. On the other hand, lump on the back of the neck caused by lymphoma is primarily treated by destroying the cancer cells through several treatment methods such as chemotherapy and radiation therapy. The information provided herein should not be used during any medical emergency or for the diagnosis or treatment of any medical condition. When a person has a salivary gland stone, most often they know this by the pain and swelling they suffer from in the gland area.
There are those people who still have salivary gland stones, yet they never show any symptoms. Therapeutic sialendoscopy utilizes a small tube with a light and camera on it, allowing a doctor to see the stone. In some cases, a small operation that cuts open the area where the stone is to remove it must be done.
On the one hand, there are countless potential causes, some of which are severe and treatable. Normal lymph nodes are usually less than 1 cm in diameter and tend to be larger in adolescence than later in life.
A clinically useful approach is to classify lymphadenopathy as localized when it involves only one region such as the neck or axilla, and generalized when it involves more than one region [1]. As will be discussed below, some node presentations suggest a specific disease process, and a few diseases present predominantly with lymphadenopathy. Posterior cervical lymphadenopathy may occur with EBV infection, tuberculosis, lymphoma, Kikuchi disease (see below), or head and neck malignancy (either lymphomas or metastatic squamous cell carcinoma). It is a common occurrence among the general population which at times causes an alarm to the patient for the fear of something else besides being harmless.

The location of lump in the neck is significant in determining what the lump is and its cause.
Lymphoma is the cancer of the lymphatic system characterized by the uncontrollable proliferation of the white blood cells in the lymph.
Most cases of lump on back of neck are benign that treatment is often not necessary although it is still important to consult a doctor for proper evaluation and diagnosis. Lump on back of neck that is caused by an infection, for example, can be treated with antibiotics, but swelling of the lymph nodes due to viral infection does not necessitate treatment and usually resolve on its own. Most cases of lump on the back of the neck are benign and the onset usually does not cause discomfort and may not affect the daily activity of life or the quality of life.
A licensed medical professional should be consulted for diagnosis and treatment of any and all medical conditions. These stones are referred to as salivary gland stone or Salivary Duct Stones, Salivary Calculi and Sialolithiasis. More times than not, this is discovered at meal times when trying to eat, as the gland is completely blocked not allowing saliva to exit. On the other, severe causes are uncommon and the best way to reach a definitive diagnosis is by biopsy, which is invasive and not justified in most cases. Lymph nodes are often palpable in the inguinal region in healthy people, perhaps because chronic trauma and infection is so common in the lower extremities, and may also be palpable in the neck (particularly submandibular) following head and neck infections. The lump at the back of the neck can be alarming but it is usually painless and harmless and which have no impact in the daily activities of an individual. These lymph nodes are an important component of the lymphatic system which is where the waste from filtered bacteria are being stored and eventually destroyed by white blood cells.
The major role of tonsil is to protect the body from any bacteria and harmful organisms that may enter the body through the throat. The injury will result in damages in the muscle, which will later protrude and form a lump, particularly at the back of the neck. The rapid and uncontrollable proliferation of the cancerous cells will result it to accumulate and form a mass or lump that can be easily palpated and seen. These can be caused by bacterial or viral infections, cancer (malignancy), or other rare causes.Enlarged lymph nodesLymph nodes are present throughout your body. Links to other sites are provided for information only -- they do not constitute endorsements of those other sites. The stone will block the saliva that flows, meaning a person can experience intense pain and swelling in the gland that has the stone. After a meal, the pain usually stays with the person for an hour or two, and can be rather intense at times due to the blockage of saliva.
When these chemicals crystallize, they form stones that can clog the salivary glands in the mouth.
Many people state they have pain and swelling in the areas, which leads doctors to diagnose the problem right then. With this method, the stones are broken up, and then sialendoscopy method is used to remove the broken stone.
The lymph nodes can swell when it is filled with too much bacteria and an infection occurred.

While the tonsil is safeguarding the body from invasion of bacteria and other harmful organisms, it can get inflamed and swell in the process due to an overload of bacteria.
When an injury to the muscle or tendon occurs, it will cause a sharp pain, stiffness and difficulty in moving the head. The accumulation of the cancerous cells and the formation of the hard mass or lump may happen at the back of the neck. There is no concrete reason for why these stones form, but in most cases, they can come out on their own or with a little probing.
Most of the stones that people have are basically nothing but hardened calcium that is crystallized from the saliva. These stones can block the glands from releasing saliva, which then causes pain and swelling since the saliva cannot get out.
In other patients, the doctors can visually see the stones due to the swelling and redness, and infection that may be in the area. If the stone is too big to remove this way, it can be broken up and each individual piece removed by the sialendoscope. It is therefore imperative to consult a physician when a lump on back of neck is noticed to determine the extent and seriousness of the condition. When this occurs, a lump will form at the front of the neck and will subsequently form a lump on back of neck as the infection progresses. In some cases, the person has to have a small procedure performed in order to remove the stone. The causes of the chemicals crystallizing vary, but there are several reasons that doctors look at. When a doctor looks in the area, they may probe the areas, which the person will then feel a lot of tenderness, which leads doctors to the assessment that salivary gland stones are to blame.
Swollen lymph nodes can cause pain and discomfort in and around the neck and can make movement of the neck rather difficult. This will result to a palpable lump on the back of the neck and other symptoms such as difficulty in swallowing, pain and the onset of fever. If there is no tenderness, if the doctor were to massage the jaw area, they may even see the stones spill out. According to the Merck Manual Home Health Handbook, those who do suffer with stones, about 25% of these people have more than one stone at a time. Glandular fever is a type of fever that is caused by an infection and can cause swelling of the lymph nodes particularly at the sides and back of neck. There are times in which doctors inject dye into the mouth in order to see any blocks that may be present.
Sore throat and common cold can also cause the lymph nodes to swell, resulting in a palpable lump. This can be caused by bacterial or viral infections, malignancy, and other rare causes.Neck lumpillustrationLymphatic system - illustration The lymphatic system filters fluid from around cells.
