Epithelioid Mesothelioma Histology

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 histology. Mutations in mesothelial cells caused by asbestos exposure create these variations. This process is part of mesothelioma pathology which involves examining either tissue or fluid to determine if this cancer exists in the body. Epithelioid mesothelioma cells have some notable characteristics. Epithelioid cell type this form of mesothelioma is the result of healthy epithelial cells in your body mutating into cancerous cells.

Asbestos exposure can mutate epithelial cells which then become cancerous. The medical term histology refers to the microscopic study of tissue. Epithelioid mesothelioma is caused by asbestos exposure and is the most common form of the disease accounting for 70 80 of diagnoses. Treatment and prognosis are affected by a patient s mesothelioma cell type.

Specialists have an easier time telling them apart from other mesothelioma cell types because of their unique appearance. Upon entering the body these asbestos fibers can lodge into cells along the mesothelium which lines the lungs abdomen and heart. They are square shaped cells and have visible nuclei plural for nucleus the center of the cell which carries genetic material. Mesothelioma histology or mesothelioma histopathology is the study of tissue for the presence of mesothelioma.

Epithelial cells are prevalent in the human body but can be irritated by asbestos. Papillary fragments and cohesive cell clusters moderate amount of cytoplasm round to ovoid nuclei prominent nuclei. Epithelioid mesothelioma is the most common mesothelioma cell type accounting for 50 to 70 of cases. The epithelial cell type is identified by the clumping of cells and a square or cubic appearance.

Consequently there are many diseases to be differentiated when the diagnosis of mesothelioma is based on histological analyses. Mesothelioma histology is the study of the function and structure of anatomy including tissues and cells. It can take many forms. The cells are slow to metastasize or spread and respond more favorably to treatment than other mesothelioma cancer cells.

Symptoms include shortness of breath and weight loss. Epithelial cells can develop in the lining of the lungs abdomen or heart. Mesothelioma can be categorized histologically as epithelioid type sarcomatoid type biphasic type desmoplastic type among others. Ayesha azam for case of the week 476 ck5 6.

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.
