Current high-resolution computed tomography (HRCT) of the thorax at the time of admittance displayed diffuse, multiple, 1-5 mm nodular lesions in the parenchyma of both lungs, with a slight predominance in the upper lobes (Figure 1).
Lung parenchyma with meningothelial cells that are solid trabecularly arranged and has a round to ovoid shape; in some places, they are fusiform (hematoxylin and eosin, 100x) (a). Immunohistochemical staining was positive for progesterone receptor (b), CD56 (c), and vimentin (d).
