Plain-English summary
A 6-year-old male English Springer Spaniel was brought in for worsening limping on his right front leg and swelling around the elbow over the past month. The vet found muscle wasting near the shoulder and a heart murmur, but blood tests were mostly normal. X-rays showed a concerning bone lesion, and a fine-needle aspiration confirmed it was chondrosarcoma, a type of bone cancer. The dog underwent amputation of the affected leg, and tests showed that the cancer had spread to nearby lymph nodes. This type of cancer spreading is unusual and may affect the dog's prognosis.

Abstract
A 6 yr old castrated male English springer spaniel was evaluated with a 1 mo history of progressive right forelimb lameness with recent swelling around the elbow joint. Physical examination findings included lameness of the right forelimb, muscle atrophy around the right shoulder, grade 2/6 heart murmur, and moderate dental disease. Results of a complete blood cell count and serum biochemical analysis were unremarkable with the exception of a mildly increased alkaline phosphatase (368 U/L; reference range, 128-328 U/L). Radiographs of the right elbow revealed a mixed lytic and proliferative osseous lesion most consistent with either neoplasia or infection. Thoracic radiographs and the echocardiogram were unremarkable. Fine-needle aspiration of the bone lesion was performed. The cytological diagnosis was chondrosarcoma. The right forelimb was amputated and the axillary lymph nodes were collected. Histopathological examination of the bone lesion and axillary lymph nodes revealed chondrosarcoma with metastasis to the lymph nodes. Lymph node metastasis of chondrosarcoma is rare and needs to be further evaluated as a prognostic indicator.
