Understanding Epithelial Mesothelioma
Epithelial mesothelioma, the most common form of mesothelioma, affects the lining of the lungs and other organs. It is characterized by the presence of epithelial cells, which line the surfaces of organs and tissues. This subtype accounts for about 70% of mesothelioma cases. The primary cause is exposure to asbestos fibers. Diagnosis involves identifying mesothelioma cells through immunohistochemistry. Common symptoms include abdominal pain, nausea, and misdiagnosis due to the similarity with other conditions. Treatment options include chemotherapy, radiation therapy, and surgery such as pneumonectomy or extrapleural pneumonectomy. Median survival varies depending on the stage and treatment. Increased awareness and research are crucial in improving the prognosis and life expectancy of epithelial mesothelioma patients.
What Is Epithelial Mesothelioma?
Epithelial mesothelioma, also known as malignant mesothelioma, is a malignant tumor that affects the thin layer of tissue surrounding the lungs, abdomen, or heart. It is the most common type of mesothelioma and is characterized by cancerous epithelial cells. This cancer develops due to long-term exposure to asbestos fibers and can cause symptoms such as chest pain, shortness of breath, and weight loss. Once asbestos fibers enter the body, the toxic particles can become lodged in the mesothelium, which is the lining of the lungs, abdomen, or heart. The mesothelium is made up of healthy epithelial cells, which means irritation of the mesothelium impacts the epithelial cells. Diseased epithelial cells of the mesothelium can turn into mesothelioma tumors.
Identifying Symptoms of Epithelial Mesothelioma
Symptoms of epithelial mesothelioma, such as chest pain, difficulty breathing, and coughing, can vary depending on the tumor's location and stage. Weight loss, fatigue, and night sweats may also occur. It is important to note that these symptoms can be similar to those of other respiratory conditions. Thus, seeking medical attention for an accurate diagnosis of symptoms of epithelioid mesothelioma is crucial. Early detection of mesothelioma enhances treatment options and prognosis. If you experience any of these symptoms, especially if you have a history of asbestos exposure, consult with a healthcare professional promptly.
Common Symptoms of Epithelial Mesothelioma
Chest pain is a common symptom of epithelial mesothelioma, usually described as a dull, aching sensation. Difficulty breathing, known as dyspnea, may occur as the tumor grows and puts pressure on the lungs. Persistent coughing can also be a symptom, sometimes accompanied by blood in the sputum. Weight loss may occur due to decreased appetite and increased energy demands from cancer growth. Fatigue and weakness are common symptoms seen in many cancers, including epithelial mesothelioma.
Diagnosis Process for Epithelial Mesothelioma
Diagnosing epithelial mesothelioma involves a combination of imaging tests, biopsies, and laboratory analysis. CT scans and MRIs are used to identify tumors and their location. A biopsy confirms the diagnosis by examining tissue samples under a microscope. Immunohistochemistry analyzes these samples to determine the specific cell type and confirm the patient’s mesothelioma diagnosis. These test results guide treatment plans and prognosis for epithelial mesothelioma patients. It's important to accurately diagnose this type of mesothelioma due to its association with asbestos exposure. Early detection of mesothelioma diagnosis can lead to more effective cancer treatment options and improved survival rates. At this point, your doctor will probably refer you to an oncologist.
Role of Immunohistochemistry in Diagnosis
Immunohistochemistry plays a vital role in the diagnosis of epithelial mesothelioma. This technique involves the use of antibodies to detect specific proteins or markers that are characteristic of epithelial cells. By analyzing tissue samples with immunohistochemistry, pathologists can accurately determine the cell type of the mesothelioma, which is crucial for guiding treatment decisions. Additionally, immunohistochemistry helps differentiate mesothelioma from other types of cancer, such as lung adenocarcinoma. It is considered a valuable tool in providing an accurate diagnosis of epithelial mesothelioma, aiding in effective treatment strategies for patients.
Rare Subtypes of Epithelial Mesothelioma Cells
Adenomatoid mesothelioma, a rare subtype of epithelial mesothelioma, commonly affects the lining of the abdomen or pelvis.

These less common subtypes may require different treatment approaches and have distinct prognoses compared to the more prevalent form of the disease. It is crucial for healthcare professionals to accurately identify the cell type of mesothelioma to determine the most suitable treatment options for patients. Assessing the specific characteristics of these epithelial mesothelioma subtypes, including the peritoneum, allows for personalized, effective care.
Adenomatoid and Small Cell Mesothelioma
Adenomatoid mesothelioma is a rare subtype characterized by glandular-like structures and a slow-growing nature. On the other hand, small cell mesothelioma is a rare subtype characterized by small, densely packed cells that resemble small cell lung cancer. Both subtypes may have different treatment approaches and prognosis compared to the more common epithelial mesothelioma cells. Accurate diagnosis of these rare subtypes is important to guide treatment decisions and determine the prognosis for patients. These subtypes highlight the complexity of mesothelioma and the importance of understanding the various cell types and their unique characteristics, including the square-shaped epithelioid mesothelioma cells with visible nuclei, for effective management.
Well-Differentiated Papillary Mesothelioma (WDPM)
Well-differentiated papillary mesothelioma (WDPM) is a rare subtype of epithelial mesothelioma that primarily affects the lining of the abdomen, although it can also occur in the lining of the lungs or other organs. This particular subtype is characterized by the presence of papillary structures, which are finger-like projections of cells. WDPM has a relatively better prognosis compared to other forms of mesothelioma, with a low rate of metastasis and longer overall survival. Treatment options for WDPM may include surgery, chemotherapy, and radiation therapy. It is essential for healthcare professionals to accurately identify the cell type of mesothelioma to determine the most appropriate treatment options for patients.
