Figure 1 Computed tomography images. A and B: Case 1 with multiple nodules in both lungs. C and D: Case 2 with a ground-glass nodule in the posterior segment of the right upper lobe apex. E and F: Case 3 with two nodules in the right lower lobe, one in the dorsal segment and the other in the outer basal segment.

Figure 2 Histologic examination images. A: Histopathological examination of case 1 showed that the adenocarcinoma was arranged along the alveolar septum in a papillary pattern [hematoxylin-eosin (HE) staining, original magnification × 100]; B: The yeast form of Cryptococcus neoformans was observed throughout the granulation tissue, with macrophage phagocytosis (HE staining, original magnification × 200); C: Periodic acid-Schiff (PAS) staining; D: PAS diastase staining.
