Plain-English summary
A 3-year-old spayed female Brittany was brought in with a cylindrical mass on the right side of her face, which developed after a small stone in her parotid duct was removed three months earlier. The dog was otherwise healthy, but tests showed a thick, yellow fluid in the mass. The vet used a carbon dioxide laser to remove the mass, which was found to be parotid duct ectasia (a condition where the duct becomes enlarged). After the surgery, the dog made a full recovery, experiencing only mild temporary facial weakness, and there have been no signs of the issue returning after four months.

Abstract
A 3yr old spayed female Brittany was referred with a cylindrical mass on the right side of her face. Three months earlier, a small stone embedded in the right parotid duct was noted and removed through a ductal incision by the referring veterinarian. At referral, the dog's general physical condition was normal except for a cylindrical mass on the right cheek. Skull radiographs showed a possibly retained sialolith or dystrophic mineralization within the previous surgical site. Aspiration of the mass yielded a thick, yellow/tan, mucopurulent fluid. Cytology of the fluid demonstrated degenerative neutrophils without bacteria. The cylindrical mass was excised with a carbon dioxide laser. The caudal end of the mass was connected to the parotid salivary gland and the rostral one-third of the mass tapered to a point. The caudal end of the mass was ligated with 3-0 polydioxanone and excised immediately rostral to the ligation. Histopathology revealed that the mass was parotid duct ectasia. The dog completely recovered with some mild temporary facial paresis and had no recurrence of parotid duct ectasia at 4 mo follow-up. The case report describes a dog with an unusual parotid salivary duct ectasia caused by parotid duct sialolith removal.
