A tongue tumor was diagnosed by the referring veterinarian in this 14 year old miniature poodle dog.  The mass extends close to the midline.

It was originally diagnosed as a granular cell tumor.

Partial glossectomy post excision

Histopathology confirmed clean margins.  The definitive diagnosis was liposarcoma .   This miniature poodle dog did excellent with no feeding tube following local blocks and a fentanyl patch.  Liposarcomas represent only 2-3% of tongue tumors in dogs (1)  They are malignant but are locally invasive and don’t tend to metastasize.
