What is a common feature of malignant mesothelioma?

Malignant mesothelioma is characterized by its histological subtypes, primarily epithelioid and sarcomatoid. Epithelioid mesothelioma typically has a better prognosis and appears as gland-like structures under microscopic examination. In contrast, sarcomatoid mesothelioma is less common and tends to have a more aggressive course. Recognizing these two types is crucial for diagnosis and determining the treatment approach.

While other traits of malignant mesothelioma include its linked association with asbestos exposure and its usual location in the pleura, the distinguishing feature of being classified into these specific histological subtypes is fundamental in the context of pathology and underscores the importance of accurate diagnosis based on tissue morphology. This understanding aids pathologists and clinicians in identifying the nature of the tumor and managing patient care accordingly.
