Malignant pleural mesothelioma with a 14-year survival: A case report and electronmicroscopic study

A patient with malignant pleural mesothelioma and surviving 15 years is presented. During this time she has had 15 thoractomies for removal of persistent tumor. The histological sections were reviewed from 1967–1981, and it was found that the tumor had remained essentially unchanged. Ten different specimens were examined electronmicroscopically; no ultrastructural changes were detected.
