Abstract
The major serosal body cavities of the thorax, pericardium, and abdomen are lined by a monolayer of mesothelial cells. The body cavity wall (parietes) and the organs (viscera) are lined by mesothelium. The pleura covers the lung and hemithorax, the pericardium covers and surrounds the heart, and the peritoneum lines most of the abdomen and envelops many of its organs. Effusions, excess fluid in a body cavity, are always due to a pathologic process and are frequently evaluated by cytology to differentiate between a benign or malignant process. Synovium is composed of two to three layers of synoviocytes that line joint cavities. This chapter discusses the cytomorphology of normal mesothelium and synovium.
