case_images: She then underwent a chest CT which showed a right lower lobe (RLL) mass (3.9 x 3.5 cm) with numerous smaller nodules throughout both lungs (CT, Figure 1).
case_images: (a) and (b) H&E: broad fascicles of bland spindle cells with entrapped scattered tubules lined by bronchoepithelial cells. (c) and (d) Immunohistochemistry, tumor cells are strongly positive for muscular marker desmin (c) and ER (d).

case_images: There were entrapped scattered mature adipose tissue and tubules lined by benign bronchoepithelial cells (Figures 2(a) and 2(b)). However, given the fact that she had a hysterectomy for uterine leiomyoma, the lesion was stained for estrogen/progesterone receptor by immunohistochemistry (Figure 2(d)).
