Epithelioid Mesothelioma Histology

Upon entering the body these asbestos fibers can lodge into cells along the mesothelium which lines the lungs abdomen and heart.

Epithelioid mesothelioma histology. The three major mesothelioma cell types are epithelioid sarcomatoid and biphasic. Epithelioid mesothelioma is the most common mesothelioma cell type accounting for 50 to 70 of cases. The epithelial mesothelioma cell type makes up more than 50 of all cases. The medical term histology refers to the microscopic study of tissue.

Symptoms include shortness of breath and weight loss. The cells are slow to metastasize or spread and respond more favorably to treatment than other mesothelioma cancer cells. Epithelioid mesothelioma histology histologically epithelial mesothelioma cells have polygonal ovoid or cuboidal cell shape. Papillary fragments and cohesive cell clusters moderate amount of cytoplasm round to ovoid nuclei prominent nuclei.

Epithelioid cell type this form of mesothelioma is the result of healthy epithelial cells in your body mutating into cancerous cells. Epithelioid mesothelioma is caused by asbestos exposure and is the most common form of the disease accounting for 70 80 of diagnoses. This form of mesothelioma is comprised of cells which resemble the normal mesothelial cells in that they are arranged in a trabecular fashion. 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. Ayesha azam for case of the week 476 ck5 6. This process is part of mesothelioma pathology which involves examining either tissue or fluid to determine if this cancer exists in the body. Mutations in mesothelial cells caused by asbestos exposure create these variations.

They are square shaped cells and have visible nuclei plural for nucleus the center of the cell which carries genetic material. Treatment and prognosis are affected by a patient s mesothelioma cell type. Mesothelioma histology is the study of the function and structure of anatomy including tissues and cells. It can take many forms.

Epithelial cells are prevalent in the human body but can be irritated by asbestos. The epithelial cell type is identified by the clumping of cells and a square or cubic appearance. Asbestos exposure can mutate epithelial cells which then become cancerous. Consequently there are many diseases to be differentiated when the diagnosis of mesothelioma is based on histological analyses.

Specialists have an easier time telling them apart from other mesothelioma cell types because of their unique appearance.
