Epithelioid Mesothelioma Histology

Epithelioid mesothelioma is the most common mesothelioma cell type accounting for 50 to 70 of cases.

Epithelioid mesothelioma histology. Symptoms include shortness of breath and weight loss. Asbestos exposure can mutate epithelial cells which then become cancerous. This form of mesothelioma is comprised of cells which resemble the normal mesothelial cells in that they are arranged in a trabecular fashion. Epithelioid mesothelioma cells have some notable characteristics.

Upon entering the body these asbestos fibers can lodge into cells along the mesothelium which lines the lungs abdomen and heart. The medical term histology refers to the microscopic study of tissue. Epithelial cells are prevalent in the human body but can be irritated by asbestos. Epithelial cells can develop in the lining of the lungs abdomen or heart.

Epithelioid cell type this form of mesothelioma is the result of healthy epithelial cells in your body mutating into cancerous cells. It can take many forms. Mesothelioma histology is the study of the function and structure of anatomy including tissues and cells. Papillary fragments and cohesive cell clusters moderate amount of cytoplasm round to ovoid nuclei prominent nuclei.

Mesothelioma can be categorized histologically as epithelioid type sarcomatoid type biphasic type desmoplastic type among others. Another subset of this field called histopathology looks specifically at the microstructure of diseased cells and tissues which is what a pathologist will focus on when studying a tissue sample to make a diagnosis. Epithelioid mesothelioma histology histologically epithelial mesothelioma cells have polygonal ovoid or cuboidal cell shape. Epithelioid mesothelioma is caused by asbestos exposure and is the most common form of the disease accounting for 70 80 of diagnoses.

This process is part of mesothelioma pathology which involves examining either tissue or fluid to determine if this cancer exists in the body. The epithelial mesothelioma cell type makes up more than 50 of all cases. The three major mesothelioma cell types are epithelioid sarcomatoid and biphasic.

The epithelial cell type is identified by the clumping of cells and a square or cubic appearance. Mutations in mesothelial cells caused by asbestos exposure create these variations. The cells are slow to metastasize or spread and respond more favorably to treatment than other mesothelioma cancer cells. They are square shaped cells and have visible nuclei plural for nucleus the center of the cell which carries genetic material.

Consequently there are many diseases to be differentiated when the diagnosis of mesothelioma is based on histological analyses.
