Bronchointerstitial pneumonia and rhinitis with proliferative and catarrhal change in a veiled chameleon (VC1). (A) Histopathology of the nasal cavity revealed abundant mucus admixed with low numbers of sloughed epithelial cells, and heterophils (asterisk) with the nasal lumen. Proliferation and lymphocytic infiltration of the nasal mucosa (arrow) was present throughout. Hematoxylin and eosin (HE), 100× magnification, 100 µm scale bar. (B) Histopathology of the lungs revealed faveolar lumena (asterisks) and bronchiolar air spaces containing numerous, large accumulations of heterophils admixed with sloughed epithelial cells, mucus and cellular debris. Multifocally, there was marked hypertrophy and hyperplasia of type II pneumocytes (arrowheads) and expansion of interstitial spaces by mononuclear and heterophilic inflammation (arrow). The trachea (not shown) was similarly affected. HE, 200× magnification, 50 µm scale bar.
