Lymphoid interstitial pneumonia

: Interstitial lymphoid pneumonia is a rare disease characterized by diffuse infiltration of lung tissue by lymphocytes and plasmocytes. The diagnosis can be only achieved by histopathological examination of the biopsied pulmonary tissue. It should be differentiated from malignant processes of the lymphatic system. Immunosuppression is the main line therapy, with prednisone, azatioprine and cyclophosphamide.
