Immunohistochemistry is not required for benign lung tumors with clear pathology, but is required if the pathology is not clear.
Immunohistochemistry is actually a pathology test, which is used to determine the nature and type of the lesion by performing specific tests on the tissue at the site of the lesion. Generally speaking, immunohistochemistry is not necessary if the general pathology has already identified a benign tumor of the lungs.
Only diamond-shaped cell tumor, lipoma and other types of lung tumors, because ordinary HE examination is difficult to give a clear diagnosis, then it is necessary to carry out further immunohistochemistry examination for identification, in order to provide guidance and basis for subsequent treatment.
