General Discussion

Lymphomatoid granulomatosis is a rare disorder characterized by overproduction (proliferation) of white blood cells called lymphocytes (lymphoproliferative disorder). The abnormal cells infiltrate and accumulate (form lesions or nodules) within tissues. The lesions or nodules damage or destroy the blood vessels within these tissues. The lungs are most commonly affected in lymphomatoid granulomatosis. Symptoms often include cough, shortness of breath (dyspnea) and chest tightness. Other areas of the body such as the skin, kidneys or central nervous system are also frequently affected.

The abnormal cells in lymphomatoid granulomatosis are B-cells (B lymphocytes) containing the Epstein-Barr virus. There are two main types of lymphocytes: B-lymphocytes, which may produce specific antibodies to "neutralize" certain invading microorganisms, and T-lymphocytes, which may directly destroy microorganisms or assist in the activities of other lymphocytes. Because lymphomatoid granulomatosis is caused by the overproduction of abnormal B-cells, affected individuals may eventually develop B-cell lymphoma, a form of non-Hodgkin lymphoma. Lymphoma is a general term for cancer of the lymphatic system.


The symptoms and progression of lymphomatoid granulomatosis vary greatly from case to case. The disorder may occasionally resolve without treatment (spontaneous remission) in some affected individuals or more commonly it will progress and cause life-threatening complications. Occasionally, it is an incidental and asymptomatic finding on chest radiographs (less than 5 percent).

In almost all cases, lymphomatoid granulomatosis affects the lungs and often causes a cough, shortness of breath (dyspnea) and chest tightness. In most patients, the cough is non-productive and is rarely associated with blood (hemoptysis). Systemic symptoms are not uncommon and may include fever, a general feeling of poor health (malaise), weight loss, and fatigue. Affected individuals may occasionally develop numbeness and tingling and/or weakness of their lower extremities.

Approximately 40-50 percent of affect individuals will develop skin lesions such as a patchy reddish (erythematous) rash consisting of flat discolored lesions (macules), small, elevated bumps (papules) or, more rarely, solid, raised, flat-topped lesions (plaques). Small bumps or growths (nodules) just below the surface of the skin (subcutaneous) may also develop. Larger nodules may become open sores (ulcerated).

In approximately 30 percent of cases, the central nervous may be involved potentially resulting in mental status changes, headaches, seizures, paralysis of one side of the body (hemiparesis), or loss of the ability to coordinate voluntary movements (ataxia).

Less commonly, the kidneys or liver may be involved, although this rarely leads to the development of symptoms. In some cases the liver may become enlarged (hepatomegaly). In some extremely rare cases, lymphomatoid granulomatosis may only affect the skin or only the central nervous system (isolated lymphomatoid granulomatosis).

Lymphomatoid granulomatosis may eventually progress to a form of large B-cell lymphoma.


The exact cause of lymphomatoid granulomatosis is unknown. Lymphomatoid granulomatosis occurs with greater frequency in individuals with some form of immune system dysfunction including individuals with Sjogren syndrome, rheumatoid arthritis or chronic viral hepatitis.

It is likely that some combination of immunodeficiency, genetic and familial factors all play a role in the development of lymphomatoid granulomatosis. The therapy used varies, but is generally directed against eliminating the EBV-infected B-cells or boosting the immune system.

The classification of lymphomatoid granulomatosis has been difficult. Originally, the disorder was viewed as a benign process with the potential to progress to malignant lymphoma. Researchers believed that defective cells were T-cells. Scientific advances in technology have allowed researchers to determine that the abnormal cells in lymphomatoid granulomatosis are B-cells infected by the Epstein-Barr virus. However, most of the cells within the tissues are T-cells, reacting against the abnormal T-cells. The Epstein-Barr virus is common among the general population and is relatively well-known because it is the cause of infectious mononucleosis (IM), usually with no long-lasting effects.

Affected Populations

Lymphomatoid granulomatosis affects males twice as often as females. It is most common in adults after the fifth decade, but can occur at any age and has been reported in children. The prevalence of lymphomatoid granulomatosis is unknown.

The disorder was first described in the medical literature in 1972.

Standard Therapies


A diagnosis of lymphomatoid granulomatosis is made based upon a detailed patient history, a thorough clinical evaluation, and a variety of specialized tests such as the surgical removal and microscopic examination (biopsy) of tissue samples taken from an affect organ such as the lungs. A skin biopsy is not reliable because the characteristic abnormal cells may be missing.

Certain x-ray studies (e.g., CT scans) may be able to aid in diagnosis. A CT scan of the lungs or another affected organ can help determine the extent of lymphomatoid granulomatosis. Magnetic resonance imaging (MRI) of the brain may be performed to rule out involvement of the central nervous system.


The most effective therapy for individuals with lymphomatoid granulomatosis is unknown. For individuals with minimal disease, observation may be recommended since long-term survival without treatment has occurred as well as spontaneous remission. In most cases, however, treatment is recommended. Treatment recommendations are mostly based on the grade of disease. Lymphomatoid granulomatosis is pathologically divided into three grades (I, II, III), which are determined by the number of EBV+ B-cells and the extend of necrosis. In patients with grade I/II disease, interferon alfa-2b has been shown to be highly effective in most patients, and leads to longterm remissions and potential cures. In patients with grade III disease, interferon alfa-2b is not effective, and combination chemothearpy with rituximab should be used. However, there is a frequent rate of recurrence with grade I/II disease following chemotherpy-rituximab in grade III disease.

Corticosteroids alone are only recommended as a temporizing measure and should not be used for long term control of lymphomatoid granulomatosis. Similarly, rituximab alone is seldom effective for long term control. Neither of these agents effectively eradicates and abnormal EBV clones and corticosteroids can increase immusuppression and ultimately disease progression.

If patients develop lymphomatoid granulomatosis on immune suppressive agents, they should be stopped if possible and the patient observed. If the disease is progressive or advanced, then treatment as outlined above should be institutued.

Investigational Therapies

Patients with grade I/II disease in the central nervous system (CNS) frequently respond to interferon alpha-2b and do not require intrathecal or high dose systemic chemothearpy. Rarely patients with CNS invovlement require brain radiation.

Researchers at the Division of Clinical Sciences of the National Cancer Institute seek additional patients for a study of treatment of Lymphomatoid Granulomatosis with interferon alfa-2b for grade I/II and EPOCH-Rituximab /Alpha-Interferon for Grade III. To participate, patients must be diagnosed with LYG, 12 or older, and not pregnant or nursing.
