文摘

Lymphomatoid granulomatosis is a rare, Epstein Barr Virus (EBV)-associated systemic angiodestructive disorder that may progress to a diffuse large B cell lymphoma. Pulmonary involvement occurs in over 90 % cases followed by kidney, skin and brain. WHO classifies lymphomatoid granulomatosis under the generic heading of B cell proliferations of uncertain malignant potential. Radiologically, pulmonary lymphomatoid granulomatosis (PLG) presents with non specific findings making histopathology the gold standard for diagnosis. The histological diagnosis of PLG includes a triad of polymorphic lymphoid infiltrates, transmural infiltration of arteries and veins by lymphoid cells (“angiitis”), and focal areas of necrosis within the lymphoid infiltrates. PLG should be distinguished from granulomatosis with polyangitis, as well as other forms of malignant lymphoma, like extranodal NK/T cell lymphoma, secondary diffuse large B-cell lymphoma and primary Non Hodgkin lymphomas of lung.
