In addition to these broad classes, mesothelioma is further categorized by the histological characteristics of the affected cells. Although the cells can be stained in order to differentiate them, most doctors consider electron microscopy to be the leading way to differentiate and identify them. There are three main types of cells including:

Epithelial Mesothelioma

Also known as epithelioid mesothelioma, is the most common subtype of mesothelioma and makes up about 50-70% of all of the diagnosed cases of mesothelioma. These cells are generally cuboidal in structure and contain an easily identifiable, darkly staining nucleus.

These cells are relatively uniform in shape and structure and are described as having tubular papillae. Epithelial mesothelioma has the best prognosis because it responds best to treatment. All types express the same symptoms.

Sarcomatoid Mesothelioma

Sarcomatoid mesothelioma is the least common main subtype of mesothelioma and is only found in 7-20% of all cases of diagnosed mesothelioma. This is the most aggressive subtype of mesothelioma; therefore the prognosis for sarcomatoid mesothelioma is generally poor.

Sarcomatoid mesothelioma can also be difficult to diagnose because the cells do not stain well. Generally they have an elongated nucleus and spindle or storiform structure.

Biphasic Mesothelioma

Also called mixed cell type contains both sarcomatoid and epithelioid mesothelioma characteristics. This cell type generally makes up about 25-30% of the mesothelioma diagnoses. The prognosis for biphasic generally falls between sarcomatoid and epithelial mesothelioma.
