Mesothelioma Plaques Calcified, Malignant Pleural Mesothelioma With Pleural Plaques A Case Report

Calcified pleural plaques from asbestos exposure.

Kid friendly jack o lantern ideas. Calcification most often affects the parietal and diaphragmatic pleura and spares the costophrenic sulci and apices. More than 60 of subjects with pleural plaques had several calcified plaques. Infection involving the pleura.

Typically with sparing of the costophrenic angles. The long term effects of this exposure are vastly different and present as two extremely opposite diagnosis based on the type and duration of exposure. Of the 1098 subjects with pleural plaques 782 712 had typical pleural plaques.

Mesothelioma vs pleural plaques. They can however lead to pleural thickening which can further decrease overall lung function. However this appears to only happen if the plaques calcify which happens in 5 to 15 of cases.

Seen in 20 usually represents engulfment of calcified pleural plaques rather than true tumor calcification 4 sarcomatoid variants may contain calcific osteosarcoma or chondrosarcomatous components an uncommon variant is the solitary mediastinal malignant mesothelioma which has appearances reminiscent of a solitary fibrous tumor of the pleura 1. However pleural plaques may be an indicator of a higher risk for cancer such as pleural mesothelioma or asbestos lung. Locations most commonly encountered include posterolateral mediastinal and diaphragmatic pleura 1.

Researchers have found that pleural plaques are rather exclusively caused by exposure to asbestos and most common among workers exposed to the toxin on the jobin some cases even those exposed to asbestos fibers for a short period of time also later developed pleural plaques. Close up x ray of calcified asbestos pleural plaques. Pleural plaques and mesothelioma are both caused by exposure to asbestos.

Overview asbestos exposure and pleural plaques. Plaque developing on lungs is considered an asbestos related disease but they are not cancerous. Pleural plaques are smooth calcified white raised irregular lesions found.

Any pleural or pericardial surface can be affected but asbestos related pleural plaques are usually in the lower two thirds of the thorax and are bilateral. Indeed several published studies have focused on the association between pleural plaques and mesothelioma mainly pathological studies and studies based on chest x ray. In this chapter the focus on two major diseases related to asbestos.

It should be noted that even when they are calcified pleural plaques are not an indication of mesothelioma asbestosis or lung cancer. Pyothoraxempyema tuberculous pleuritis 3. Calcified plaques are more obvious than non calcified plaques to be identified.

Pleural calcification can be the result of a wide range of pathology and can be mimicked by a number of conditionsartifacts. Pleural plaques and malignant mesothelioma.
