[Pleuromesothelioma -- psychology and pathogenesis].
Investigations into the anatomical pathology are of crucial importance for the diagnosis and therapy of pleural tumours. The main objective is to differentiate reactive hyperplastic proliferations of the mesothelium from already manifest primary or secondary malignant pleural tumours. Given the absence of distinct morphological features displayed by pleural mesotheliomas, specific additional immunohistochemical and cytometric tests can provide valuable clues for the differential diagnosis of primary and secondary pleural neoplasms. Confirmation of the diagnosis during the initial stages of tumour development i. e. mesothelioma in-situ and early mesothelioma necessitates invasive diagnostic procedure as early as possible. This holds particularly true if surgery is aimed at cure. However, in order to firmly establish the diagnosis considering the afore mentioned problems, the tissue specimens to be examined by a pathologist must be of adequate size. 90 % of all pleural mesotheliomas are asbestos associated due to occupational exposure. Therefore, all cases of a suspected pleural mesothelioma must be reported to the appropriate professional association as a potential occupational disease. The Bochum based German Mesothelioma Registry, which is supported by the head office of the German Professional Associations, conducts research and acts as an advisory institution in difficult cases, where problems concerning the classification of tumours by their anatomical pathology arise.
