POX-052A.jpg

tissue_organ_import: 
trachea
Morphologic diagnosis: 
Trachea: Diffuse tracheitis with locally extensive diptheritic membrane.
Clinical description: 
This image shows typical diphtheritic lesions on the trachea, caused by avian pox. The fibrino-necrotic proliferative lesions form on mucous membranes. In the early stages, these plaques begin as as small white opaque nodules that frequently enlarge into larger yellow diptheritic membranes. These lesions may develop in the oral cavity, tongue, esophagus, or upper trachea. If the lesions are located in the lower respiratory tract (e.g. the syrinx), they can compromise breathing, resulting in dyspnea.
Pathologic description: 
The trachea has been opened to reveal the mucosal surface. The proximal trachea is covered by a large coagulum of pale yellow, friable material that is adherent to the underlying mucosa. The remaining tracheal mucosa is red, glistening and undulating.
