Case report: Sublingual mucinosis in a dog

Area of Science:

• Veterinary Medicine
• Oral Pathology

Background:

• Bilateral sublingual swellings, initially suspected as ranulas, presented in an 11-month-old intact male Shar-Pei.
• The condition had persisted for 4 months prior to presentation.

Observation:

• Surgical exploration revealed gelatinous tissue without saliva, inconsistent with typical ranulas.
• Histological examination confirmed the diagnosis of oral mucinosis.

Findings:

• Two surgical excisions, performed 4 weeks apart, were curative.
• The dog showed no signs of recurrence during an 8-month follow-up period.

Implications:

• This case establishes oral mucinosis as a differential diagnosis for sublingual swellings in dogs.
• Surgical management appears to be an effective treatment for canine oral mucinosis.
