Figure 2. Histologic sections showing multiple well-circumscribed interstitial meningothelial-like nodules (arrows) with the predominant perivenular distribution. The nodules are composed of oval-to-spindle cells with indistinct cellular borders and uniform oval nuclei. Whorling of the tumor cells can also be appreciated. Overall, the morphologic features are consistent with diffuse pulmonary meningotheliomatosis.
