Pharyngeal Lymphoid Hyperplasia
Equine pharyngitis, also known as pharyngeal lymphoid hyperplasia, is a condition in which the diffusely located lymphoid tissue enlarges. This enlargement causes numerous small bumps on the surface of the pharynx.
Most of the time the inflammation is caused by a viral or bacterial infection and tends to be mild and self-limiting. If severe, it can affect the normal function of the pharynx, resulting in pharyngeal collapse of dorsal displacement of the soft plate.
