Fig. 3. Histopathologic findings of chordoid meningioma of the lung. (A) Gross examination revealed a well-demarcated, gray-white solid mass with a hard consistency. (B) On microscopic examination, the tumor was sharply demarcated (H&E, ×12.5), and (C) it showed cord-like and solid tumor cell nests within abundant mucous-rich stroma (H&E, ×200). (D) The tumor cells often showed epithelioid features with vacuolated cytoplasm (H&E, ×400). The tumor cells had diffuse immunoreactivity for epithelial membrane antigen (E, ×100) and vimentin (F, ×100).
