Diagnosis:
According to the patients can have a history of asbestos exposure history. Physical examination found diminished breath sounds and percussion dullness prompt pleural effusion, or tumor growth in the advanced observation and palpation of chest wall, in particular the intercostal, we find that tumor swelling, suggesting that invasion of chest wall tumors. Combination of laboratory tests and chest CT examination can determine if the pleural calcification or bone structure, has damaged the health of search. Malignant pleural mesothelioma should be considered possible . But in order to diagnosis, need further examination and pleural effusion by pleural biopsy to be determined. Network currently in use cupping technique video-assisted thoracoscopic biopsy diagnosis rate of up to 100% of surgical risk and mortality rates are low, an alternative to exploratory thoracotomy biopsy.
Differential Diagnosis:
Although the pleural effusion smears, breast and wearing a pleural biopsy and pleural effusion cell block sections can make the diagnosis of malignant cupping network, but can not identify metastatic adenocarcinoma and malignant pleural mesothelioma ù primarily by light microscopy electron microscopy, histochemistry, immunohistochemistry, hyaluronic acid measurement methods such as differentiated from metastatic adenocarcinoma with pleural.
Is relatively sure that the diagnosis of malignant mesothelioma, there are three kinds of technology, namely, periodic acid - Schiff staining liquid to do in order to keratinocytes and carcinoembryonic antigen for the immune peroxidase test and electron microscopy. To carry out these checks, biopsy specimens must be immediately fixed with neutral formalin solution, another small piece of tumor biopsy specimens destined for the glutaraldehyde solution for electron microscopy using the
1. Periodic acid - Schiff stain (PAS) is the only reliable histochemical method can distinguish between malignant pleural mesothelioma and adenocarcinoma metastatic adenocarcinoma, although the characteristics of a variety of different, but after amylase digestion strong positive vacuole, can be diagnosed with malignant pleural mesothelioma than adenocarcinoma.
