A 4-year-old male mixed-breed dog was presented to the clinic with a progressive swelling under the tongue that had been noticed by the owner over the past 10 days.

• Oral examination: Revealed a fluctuant, dome-shaped, translucent swelling located on the right side of the sublingual mucosa, consistent with a sublingual ranula.
• The lesion was non-painful on palpation, and no purulent discharge was observed.
• General condition: Normal appetite (with some discomfort), no fever, no lymphadenopathy.

• Fine-needle aspiration (FNA): Yielded thick, clear mucinous fluid, typical of saliva.
• Cytology: Few macrophages and amorphous eosinophilic background (salivary mucin).
• Ultrasound: Localized cystic cavity beneath the sublingual mucosa without deep gland involvement.

Surgical Procedure : Marsupialization

• During exploration, a small glass shard (foreign body fragment) was identified embedded within the ductal tissue and was carefully removed.
