Lymphomatoid granulomatosis (LYG or LG) is a very rare lymphoproliferative disorder first characterized in 1972. Lymphomatoid means lymphoma-like and  granulomatosis denotes the microscopic characteristic of the presence of granulomas with polymorphic lymphoid infiltrates and focal necrosis within it. LG most commonly affects middle aged people, but has occasionally been observed in young people. Males are found to be affected twice as often as females. Causes
Lymphomatoid granulomatosis involves malignant B cells and reactive, non-malignant T cells and is almost always associated with infection of the malignant B cells by the Epstein-Barr virus; it is therefore considered to be a form of the Epstein-Barr virus-associated lymphoproliferative diseases. The disease is believed to be induced by a combination of Epstein Barr virus infection and immunosuppression through immunosuppressive drugs (with case reports of methotrexate and azathioprine), infections such as HIV or chronic viral hepatitis or endogenous T cell defects. Pathophysiology
The onset of the disease results in proliferation of EBV-infected malignant B-cells and a cytotoxic T-cell response which in turn leads to organ infiltration and dysfunction of the affected organs. The disease typically always relapse after successful treatment due to inability of the immune system and current viral drugs to eliminate an EBV-infection. If the onset of the disease can be linked to use of immunosuppressive drugs then discontinuation of these drugs may hinder a relapse. Organs usually affected are the skin, lungs, central nervous system while liver and kidney are affected to lesser extent.
