Figure 1. :Radiological and histopathological features of LAM.

1A: High-resolution chest CT images from a patient with LAM demonstrating the characteristic thin-walled, round, uniform cysts. 1B: Histopathology demonstrating a cystic air filled space (star) lined by LAM cells (arrow). 1C: High-power view demonstrating the LAM cells surrounding the cystic space. Notice the characteristic epitheloid and spindle shaped morphology of these cells. These cells stained positive for smooth muscle cell markers (stains not shown) as well as HMB-45 (1D).
