Figure 2
Lymphangioleiomyomatosis (LAM) of lung. In a gross section, multiple cysts are shown in the left lower lung (a). In the HE staining, a dramatic loss of the alveolar septum is associated with an increasing number of cysts. In the cysts, LAM cells are observed to increase in number along the peribronchiole or perilymphatic duct (b). The cytoplasm of the LAM cells is positive for HMB45 (c).
