[Pathological diagnosis--practical treatment of surgical specimens with lung cancer].
The importance of gross examination before histology of the surgically removed lung cancers was stressed by depicting the practical methods of formalin filling fixation, slicing the specimens, drawing and noting the findings, photographing, and cutting the tissue blocks. On gross examination of the sliced specimens it was guided that besides the pathological features of cancers themselves, secondary changes such as bronchiectasis, obstructive pneumonia, hemorrhagic infarction etc, background lesions such as anthracosed scar, honeycombing etc, or apparently independent lesions like centrilobular emphysema should be described, and then not occupying but arising site of cancer should be decided on each case, expressing by the bronchial branching number and generation in central cases and the segment number in peripheral ones.
