Alveolar wall revealing cuboidal type 2 pneumocytes, thickened epithelial and capillary basement membranes (asterisks), collagen (col) bundles, and elastic fibers (el), as, Alveolar space; ep, epithelial lining; and ca, capillary (case 1) (uranyl acetate and lead citrate, original magnification × 2,600).

4. Figure 3
Alveolar tissue. Epithelial alveolar lining cells are lifted from their basement membrane, which is largely disrupted between two arrowheads, ca, Capillary; f, fibroblast; ep, epithelial cell; as, alveolar space; ic, inflammatory cells; and m, macrophage (case 5) (uranyl acetate and lead citrate, original magnification × 2,300).

5. Figure 4
Area with prominent intra-alveolar organization. Areas of intra-alveolar fibrosis (asterisks) are less cellular than remaining alveolar structures (case 4) (hematoxylin-eosin, original magnification × 125).

A (left), Immunofluorescent micrograph of alveolar walls stained by antibody to collagen type 4. Note disruption of type 4 collagen along basement membrane (lower half) compared to relatively normal areas (upper half) (case 4) (original magnification × 400). B (right), Immunofluorescent micrograph of alveolar walls stained by antibody to collagen type 3, showing positive reaction in interstitium and within alveolar space (case 4). (original magnification × 250).
