Bronchogenic Carcinoma - (PH 1240)
(Be able to identify the slide of lung cancer; differentiate between slides of normal and diseased lung.)

Note that the cancerous neoplasm is invading throughout the lung and replacing normal lung tissue. Note that in many areas the alveolar walls are thickened and many air spaces are filled with cancer cells.

Normal lung (40X2.0)                                                                      Lung with cancer (40X2.0)

Contains mostly thin membranes, open air-filled                   Contains thickened membranes, many spaces filled
spaces, large vessel (far left) and large airway                       with cancer cells.

Normal lung (100X2.0)                                                                       Lung with cancer (100X2.0)

Contains mostly thin membranes, open air-filled                   Contains thickened membranes, cancer cells fill many
spaces, and many small vessels (bright red)                          air spaces and vessels
