With the extensive industrial use of asbestos in this century and the long latent period (20-50 years) between exposure and tumor presentation, the incidence of malignant mesothelioma is now increasing. Thus, surgical pathologists are more frequently faced with the dilemma of differentiating mesothelioma from metastatic adenocarcinoma and spindle-cell sarcoma involving serosal surfaces. Electron microscopy is amodality useful in clarifying this problem.In utilizing ultrastructural features in the diagnosis of mesothelioma, it is essential to appreciate that the classification of this tumor reflects a variety of morphologic forms of differing biologic behavior (Table 1). Furthermore, with the variable histology and degree of differentiation in mesotheliomas it might be expected that the ultrastructure of such tumors also reflects a range of cytological features. Such is the case.

Malignant Neoplasia

Mesothelial cells constitute the lining of the three serous sacs of the body i.e. the pleura, pericardium and peritoneum. The more common type of malignant neoplasia of the serous sacs is seeding by metastatic tumors and primary malignancy of the mesothelium is unusual. Of the three sacs, the pleura is the most common site of malignant mesothelioma. Involvement of the peritoneum is extremely rare.We report 3 cases of malignant mesothelioma of the peritoneum. All of them were female. Their ages were 57, 67 and 72 years, respectively. The patients presented with abdominal discomfort and/or ascites. The extent of the tumors ranged from a peritoneal implant to widespread infiltration of the peritoneum and omentum. Histologic examination in Case 1 showed the presence of a diffusely infiltrating papillary mesothelioma without a sarcomatoid component. A mesodermal element was present in the other two cases. In order to establish a morphological diagnosis of malignant mesothelioma, the possibility has to be excluded of a metastatic adenocarcinoma.
