This high-resolution histopathological image depicts Sarcomatoid Mesothelioma tissue stained to reveal its defining microscopic features. The image shows elongated, spindle-shaped tumor cells arranged in a haphazard pattern, often with prominent nucleoli and a fibrous background. Sarcomatoid Mesothelioma is a rare and highly aggressive form of asbestos-related cancer, making up approximately 10–20% of mesothelioma cases. It is frequently more resistant to treatment and carries a poorer prognosis than other subtypes.
