Bovine papular stomatitis Bovine papular stomatitis Bovine papular stomatitis is a disease caused by a virus of the family "Poxviridae" and the genus "Parapoxvirus". It occurs worldwide in cattle. Symptoms include reddish, raised, sometimes ulcerative lesions on the lips, muzzle, and in the mouth. It usually occurs before the age of two years. Reinfection is possible because of the short duration of immunity. Clinically, the disease is mild, but its importance lies in the need to differentiate it from foot-and-mouth disease. There have been reports of both lesions on the hands of milkers and similar infections in sheep and goats, as well as
Stomatitis necrotizing ulcerative gingivitis, or a more severe form (also termed necrotizing stomatitis). The term "necrotizing gingivostomatitis" is also sometimes used. Also called smoker's palatal keratosis, this condition may occur in smokers, especially pipe smokers. The palate appears dry and cracked, and white from keratosis. The minor salivary glands appear as small, red and swollen bumps. It is not a premalignant condition, and the appearance reverses if the smoking is stopped. Chronic ulcerative stomatitis is a recently discovered condition with specific immunopathologic features. It is characterized by erosions and ulcerations which relapse and remit. Lesions are located on the buccal mucosa
