case_images: Chest computed tomography revealed a huge multiseptated cystic and solid mass containing foci of intralesional calcifications in the left lower lobe of the lung (Fig. 1).
case_images: (A) Gross photograph of the lower lobe of left lung shows a large cystic and solid mass containing variable size of multilocular cysts and solid component with numerous interstitial cartilaginous small nodules. (B) Multilocular cystic spaces with intervening lobulated fragments of cartilaginous tissue and hyalinized stroma (H&E stain, original magnification x1). (C) There are islands of mature cartilage, adipose tissues and immature mesenchymal tissue containing spindle cells within the intervening stroma (H&E stain, original magnification x100).

case_images: On gross examination, a huge cystic and solid mass containing variable size of multilocular cysts and solid component with numerous interstitial cartilaginous small nodules was found and occupied the superior segment and the upper portion of basal segment, measuring 11.5x10 cm in size (Fig. 2A). Microscopically, multilocular cystic spaces with intervening lobulated fragments of cartilaginous tissue and hyalinized stroma were seen (Fig. 2B). There were also foci of mature adipose tissues and a few spindle cells within the intervening stroma (Fig. 2C).
