Plain-English summary
A 4.5-year-old male Labrador Retriever was brought in for lameness in his right front leg and painful swelling around the elbow that had been going on for a month. X-rays showed a growth in the joint area, leading to a diagnosis of synovial osteochondromatosis, which is a condition where cartilage forms in the joint lining. Unfortunately, after 20 months, the dog's condition worsened, and the leg was amputated due to the development of a chondrosarcoma, a type of cancer. This case highlights the potential for synovial osteochondromatosis to turn into a more serious issue.

Abstract
A 4.5-year-old intact male Labrador Retriever dog had a 1-month history of right forelimb lameness with painful swelling of the elbow. The radiographic findings of increased synovial mass with mineralized opacities and the gross and histologic findings in the synovial biopsy specimens were consistent with a diagnosis of primary (idiopathic) synovial osteochondromatosis. Twenty months after initial presentation, based on progression of clinical signs and radiographic evidence of marked bone lysis in the distal aspect of the humerus and proximal aspects of the radius and ulna, the affected leg was amputated. The histologic diagnosis was chondrosarcoma with fibroblastic differentiation and bone lysis. The chondrosarcoma was interpreted as malignant transformation of primary synovial osteochondromatosis.
