Plain-English summary
An eight-year-old spayed female golden retriever was brought in for worsening lameness in her right hind leg and increased thirst and urination. The vet found several soft tissue masses in her hind leg muscles, and tests confirmed she had a type of cancer called extraskeletal chondrosarcoma. To treat her, the vet performed an amputation of the affected leg and started chemotherapy. After surgery, her excessive thirst and urination improved within two weeks, but follow-up X-rays later showed multiple lung lesions, likely cancer spread, and the dog was lost to follow-up after that.

Abstract
An eight-year-old, spayed, female golden retriever was presented with progressive right hindlimb lameness and polyuria/polydipsia. Multiple soft tissue masses were palpable within the hindlimb muscles. A tentative diagnosis of sarcoma was made on fine needle aspiration. A computed tomography scan of the hindlimb and thorax confirmed the presence and location of the masses, none of which were associated with the bones of the hindlimb. In addition, two pulmonary lesions were identified in the right cranial lung lobe. A diagnosis of chondrosarcoma was confirmed on histopathology with a final diagnosis of extraskeletal chondrosarcoma. A high, hindlimb amputation was performed, and chemotherapy was initiated. Polyuria and polydipsia resolved 2 weeks postoperatively. Numerous lung lesions, suspected to be metastases were found on routine followup radiographs, 73 days post surgery after which the dog was lost to follow-up.
