[Lymphoid infiltrates in the lung].

The authors reviewed material of 10 year period (1980-1990) of the Department of Pulmonology, Albert Szent-Györgyi University of Medicine, Deszk, Hungary, and selected 14 patients from the files who considered to belong in one of the lymphoproliferative conditions (4 low grade and 4 high grade lymphomas of B-cell type, 1 angiocentric, 1 mediastinal lymphoblastic non-Hodgkin's lymphoma, 3 Hodgkin's lymphoma cases and 1 pleural pseudolymphoma). Every patient admitted with prominent pulmonary symptoms. The diagnoses were based on histology and immunohistochemistry of tissue samples and autopsy. One high grade B-cell and the angiocentric malignant lymphoma proved to be primary pulmonary process. No specific radiomorphological signs were found, which could be characteristic for the pulmonary lympho-reticular infiltrations and also to distinct the primary and secondary ones. The lung infiltrations in the most of the non-Hodgkin's lymphoma cases with low grade malignancy appeared imitating tuberculosis, while the high grade group and Hodgkin's lymphomas displayed confusion with any primary or multiple tumors.
