Computed tomography of the chest showed randomly distributed tiny nodules (1-2 mm in size) in both lungs [Figure 1], with mild hepatomegaly and a few subcentimetric lymph nodes at the porta and retroperitoneum.
Gross appearance of the flexible FB (left) and CB tissue (right). The difference in the sizes can be easily appreciated

The CB was 0.5 cm in length, while the largest conventional FB specimen was 0.1 cm [Figure 2].
(a and b) Photomicrographs showing comparison of sizes of the flexible FB and CB under scanner view [hematoxylin and eosin (H and E), x40], (c) FB showing single focus of loose collection of epithelioid cells forming granuloma (H and E, x200), (d) CB showing well-formed epithelioid cell granuloma with Langhans giant cells and central necrosis with nuclear debris (H and E, x200)

Both the specimens revealed the presence of epithelioid cell granulomas with multiple Langhans type of giant cells and surrounding lymphocytes [Figure 3].
