Electron microscopic features of a Clara cell type (A) (Case 6) and a mixed type adenocarcinoma (B) (Case 5). A, peg-shaped or low columnar epithelial cells have many dense secretory granules and rough endoplasmic reticulum in their cytoplasm. B, carcinoma tissue comprises type II alveolar epithelial cells containing lamellar bodies in the cytoplasm (arrowheads) and Clara cells having dense secretory granules (small arrows) (double staining with uranium acetate and lead citrate; original magnification, × 2500).
