Objectives: To identify clinical, ultrasonographic and histopathological features of cervical sialoceles (salivary mucoceles) in dogs.
Design: Retrospective study. Animals: Three German shepherd dog.
Procedures: Case records of three dogs that underwent surgery to remove a cervical sialocele at the University of Tehran Small Animal Hospital were reviewed for signalment, clinical signs, Ultrasonographic findings and histopathology.
Results: The dogs were male German shepherd with
average age of 4 years. In all dogs, the masses were
located in the right cranioventral cervical region.
Ultrasonography showed echo texture masses with accumulation of fluid. The masses removed surgically.
Macroscopically, the masses were round, relatively
labulated, and fluctuant with a thick, fibrous capsule.
Microscopic examination revealed parotid sialocele in
one case and mandibular sialocele in the other two cases.
Coagulative necrosis in one case and secondary infection in the other were observed. There were no recurrences of the masses after at least 6 month to 2 years from the operation.
Clinical implications: Comparison of these results with studies by other authors showed that surgical excision of affected salivary glands is the treatment of choice for sialocele. Histopathologically, the wall of sialoceles consists of an outer, highly vascularized layer of immature connective tissue and an inner zone of loosely arranged fibroblasts. A pleocellular inflammatory reactionis evident in the central area, which also contains much amorphous acidophilic or amphophilic debris. J.Fac.Vet.Med.Univ.Tehran. 60,2:117-123,2005.
