In the pulmonary interstitium, granuloma maturation is accompanied by increasing numbers of lymphocytes in the bronchoalveolar lavage (BAL) fluid.
Pulmonary lymphangioleiomyomatosis (LAM), a disease of women, is characterized by (1) proliferation of abnormal smooth muscle cells (LAM cells) in the pulmonary interstitium and along axial lymphatics and lymph nodes of the thorax and abdomen, (2) parenchymal cysts throughout the lungs, and (3) a high incidence of angiomyolipomas.
The presence of edema fluid in the pulmonary interstitium and in the alveoli increases the distance across which oxygen molecules must diffuse to enter the blood.
Mild to moderate perivascular infiltrates of lymphocytes, plasma cells, and heterophils were seen within the kidney and heart, and similar but fewer numbers of infiltrates were seen within the pulmonary interstitium.
