Plain-English summary
A 6-year-old male Labrador retriever was brought in for limping on his right front leg, which started 5 years after he had surgery for a condition called osteochondritis dissecans (OCD) in the same area. X-rays showed a large, abnormal growth in the bone, and a biopsy confirmed it was osteosarcoma, a type of bone cancer. The dog underwent amputation of the affected leg to remove the cancer. This case highlights a rare occurrence of bone cancer developing in an area previously affected by OCD.

Abstract
A 6-year-old, male Labrador retriever was presented for lameness of the right forelimb. The lameness occurred 5 years after the dog was surgically treated for osteochondritis dissecans (OCD) of the caudal right humeral head. Radiographs revealed an expansile, osteolytic lesion occupying the entire caudal half of the right humeral head, and biopsy confirmed the diagnosis of osteosarcoma. Forelimb amputation was performed. Histopathology of the lesion and associated articular cartilage revealed neoplastic osteoblasts extensively infiltrating the marrow space adjacent to scar tissue associated with the previous OCD lesion. This is the first report of an epiphyseal osteosarcoma in the area of a previous OCD lesion in a dog.
