A dog developed parotid duct ectasia after sialolith removal. Surgical excision successfully treated the condition, with no recurrence observed.
Area of Science:
- Veterinary Medicine
- Surgical Pathology
Background:
- A Brittany dog presented with a facial mass following prior surgery for a parotid duct stone.
- The mass was a cylindrical swelling on the right cheek, near the parotid duct.
Observation:
- Skull radiographs suggested a retained sialolith or mineralization at the surgical site.
- Aspiration revealed mucopurulent fluid, and cytology showed degenerative neutrophils without bacteria.
- Surgical excision using a carbon dioxide laser was performed on the mass.
Findings:
- Histopathology confirmed the mass as parotid duct ectasia.
- The dog recovered fully with temporary facial paresis.
- No recurrence of parotid duct ectasia was noted at a 4-month follow-up.
Implications:
- This case highlights an unusual presentation of parotid duct ectasia secondary to sialolith removal in a dog.
- Successful surgical management and follow-up suggest a favorable prognosis for similar cases.
- The report contributes to understanding rare salivary duct complications in veterinary surgery.
