case_images: The macroscopic examination of the lung segmentectomy resection, performed using an automatic surgical stapler, revealed dimensions of 6 cm x 5 cm x 6 cm (Figure 4).
case_images: (A-D) Histopathological findings showing alveolar septa (A) with a fragment of emphysematous bulla wall (C) and intraluminal presence of vascular/capillary structures with a papillary appearance and with proliferation of associated pneumocytes reminiscent of placental chorionic villi (B/D)

case_images: The anatomic-pathological examination of the surgical piece reported papillary proliferation outbreaks of pneumocytes with histological details of pulmonary placental transmogrification (Figure 5).
