Histological examination of the submucosal endobronchial nodule. A, C Hematoxylin and eosin (H&E) staining (A scale bar = 500 μm; C scale bar = 100 μm). Microscopic evaluation of a biopsy specimen of the tumor in the left upper bronchus showed a leiomyoma with a fascicular and interlacing arrangement of spindle cells, but without nuclear atypia, covered by bronchial epithelium (A, C). B, D Desmin staining. (B scale bar = 200 μm; D scale bar = 50 μm). Immunohistochemically, the spindle-shaped tumor cells were positive for desmin (B, D)
