ABSTRACT
Haghighi S, Moaddab
SH, Afshari E., Parotid duct
salivary stone in a horse: a case report, Onl J Vet
Res., 27 (10): 546-549, 2023. Sialolithiasis accounts for most
salivary gland obstruction in horses. Salivary stones mostly affect older
horses and parotid duct is most commonly involved. A 15 year old mixed-breed
mare presented with a firm movable mass near rostral edge of right facial crest
without clinical signs or pain by palpation. There were no attachments or
adhesions to underlying, overlying tissues or bone. Antibiotic was given to
control sialolithiasis infection. To remove sialolith, an intraoral incision was made directly on stone
removed by grasping clamp and incision left open for drainage of duct. The
white 5x3 cm diameter sialolith had concentric onion
type depositions. Parotid biopsy for microscopy revealed chronic sialadenitis with mixed inflammatory cell infiltration,
acinar necrosis and fibrosis. Images of condition are provided.
