Morphological aspects of mesotheliomas after intratracheal instillations of fibrous dusts in Syrian golden hamsters.

After intratracheal instillation of glass fibres and crocidolite in male Syrian golden hamsters, besides lung carcinomas a number of mesotheliomas of the epitheloid type occurred. These were examined with light microscopy (LM) and scanning electron microscopy (SEM); the characteristics of the tumours are described.
