Chondrosarcomas are common tumors of the canine appendicular and axial skeleton; however, extraskeletal chondrosarcomas are very rare. Herein we report a case of extraskeletal chondrosarcoma in the tongue of a dog. Histologically, glossal skeletal muscle was infiltrated and effaced by islands of cartilage and streams of spindle-shaped cells. Retrospective analysis of 236 tongue masses submitted to the Iowa State University surgical biopsy service between 2011 and 2019 showed that the majority of submitted tongue masses are either non-neoplastic or benign, with granular cell tumors identified as the most prevalent benign neoplasms. Malignant tumors accounted for nearly 30% of all submitted masses, with malignant melanoma diagnosed most frequently.
