Histopathological examination of a cat lung infected with Aelurostrongylus abstrusus. Macroscopic consolidated areas correspond histologically to lung tissues presenting massive cellular infiltration: lymphocytes (green arrows), macrophages (red arrows), multinucleated giant cells (black arrow), epithelioid histiocytes (yellow arrows) as well as eosinophils (orange arrows) and plasma cells (blue arrow) are densely packed forming granulomas. Alveolar lumina are obliterated and sections of parasitic eggs and larvae (dotted black arrows) are visible. Haematoxylin and eosin. Scale-bar: 50 μm
