Title: Trophoblast cell in lung alveolar interstitium (human, early midpregnancy)
Description: Stain: Hematoxylin-eosin.
It is well known that free circulating trophoblast cells can be found migrated into lung parenchyma during normal pregnancy. In this sample a large trophoblast cell (→) is localised within the normal alveolar interstitium. Alveolar phagocytes (*) are present in the alveolar lumen.
