Pleural mesothelioma associated with indoor pollution of asbestos.

摘要

This case report concerns a 46-year-old woman, dying from histologically confirmed diffuse malignant mesothelioma after asbestos exposure, which was only caused by indoor pollution from crocidolite-containing spray asbestos in building materials. There was no other known occupational or environmental asbestos exposure during her life. The lung tissue fibre analysis by light microscopy showed significantly increased concentrations of ferruginous bodies (3162 FB per gram of wet lung tissue). By use of scanning transmission electron microscopy, clearly increased concentrations of amphibole fibres (8.6 x 10(6) fibres longer than 1 microm and 0.6 x 10(6) fibres longer than > or =5 microm per gram dry tissue), mainly classified as crocidolite, were observed. The disease was attributed to indoor exposure to sprayed asbestos, which occurred during her work as a decorator in the studio of a warehouse.
