Plain-English summary
A 13-year-old female Yorkshire terrier was having trouble swallowing due to a mass on her tongue that grew quickly over a month. The mass was located in the area under her tongue and was made up of fat and cartilage tissue. After examining the mass, the vet diagnosed it as a chondrolipoma, which is a type of tumor. This case is notable because it's the first report of this kind of tumor appearing in that specific area of a dog's mouth.

Abstract
A 13-year-old female Yorkshire terrier was presented with difficulty swallowing because of a lingual mass, which had grown to a size of 0.8 × 0.8 × 0.8 cm in 1 month. Grossly, the mass was located in the lingual frenulum and the cut surface was grey-white in colour. Microscopically, the mass was unencapsulated and composed of lobules of mature adipose tissue and cartilaginous tissue with abundant basophilic myxoid matrix separated by fibrous connective tissue. Immunohistochemically, almost all of these cells were positive for vimentin and S100. Chondroid cells and their adjacent spindle cells were also positive for SOX9. Based on these findings, a diagnosis of chondrolipoma was made. To the best of our knowledge, this is the first report of a chondrolipoma originating as a primary tumour in the lingual frenulum of a dog.
