1. Epithelial Mesothelioma
In addition to the location and whether the disease is malignant or not, the type of cells also differs among mesotheliomas. Epithelial mesothelioma cells are organized and structured, as well as the most common cell types, accounting for about 50 to 75% of all cases. These types of cells can be seen microscopically as uniformly shaped, with an elongated pattern and visible nuclei. Epithelial mesothelioma cells are the ones that develop on any of the mesothelial linings.
