title: Periarteritis in a beagle colony.
abstract: Primary periarteritis, an uncommon necrotizing vasculitis in the dog, was found to affect, almost exclusively, the major branches of the coronary arteries in a number of young beagle dogs. The arteritis was mainly distributed in the proximal segment of the right coronary artery. Immunocytochemical studies failed to identify immunoglobulin deposits in the lesions and the cause of the arteritis remains unknown. It is important to be aware of this spontaneous condition and its regional distribution since certain cardiovascular drugs may also produce necrotizing arteritis at similar sites.
