Histology of Salivary Gland Infarction in the Dog

Abstract

Salivary gland infarction was found in two adult dogs. The main changes were ischaemic necrosis, capsular fibrosis and regenerative hyperplasia of surviving ductal epithelium. Necrosis of arterial tunica media and thrombosis were found only in the infarcted parts of the salivary glands. The lesions appeared to be confined to the salivary glands; no cause of the infarction was found.
