Abstract
The histopathological appearance of malignant mesotheliomas with osseous and cartilaginous differentiation is described in detail. Bone and cartilage occurred in mixed and sarcomatoid mesotheliomas which were induced by intraperitoneal injection of various types of asbestos fibres (asbestos cement, crocidolite, UICC-amosite, UICC- chrysotile B, Calidria-chrysotile). Bone or cartilage were found in 32.7% of mixed mesothelioma and in 12.8% of sarcomatoid mesotheliomas.
