What is Well Differentiated Papillary Mesothelioma?

Well Differentiated Papillary Mesothelioma is an abdominal mesothelioma growth that is commonly associated with fluid buildups (effusions) and severe abdominal pains. The symptoms associated with differentiated papillary mesothelioma are typically not malignant—the disease is significantly milder than other forms of mesothelioma. Because of these mild symptoms, well differentiated papillary mesothelioma is frequently detected during routine check-ups or treatments for other conditions. 

Well differentiated papillary mesothelioma is a form of epithelial mesothelioma categorized by an abnormal papillary growth pattern. Well differentiated papillary mesothelioma almost always originates in the lining of the stomach, the peritoneum. Only a small percentage of the disease’s tumors are located in the lining of the testicles (the tunica vaginalis). Well differentiated mesothelioma is a combination of malignant lesions and benign tumors. 

Well differentiated papillary mesothelioma is often confused with papillary carcinomas of the peritoneum or ovaries. To properly diagnose the condition, a microscopic examination is necessary. Well-defined papillary mesothelioma cells are only identifiable by proliferations with an extension of the mesothelium cell. 

Who is at Risk for Well Differentiated Papillary Mesothelioma? 

Although well differentiated papillary mesothelioma is more common in males than females, the papillary variant of the condition is predominantly diagnosed in premenopausal women between the ages of 30 and 40. Dissimilar to most forms of malignant mesothelioma, well-differentiated papillary mesothelioma is not associated with asbestos exposure.
