Plain-English summary
A 6-year-old neutered male Rottweiler was brought in for worsening limping on his right back leg. X-rays showed a serious bone issue in his kneecap, and further tests revealed that the cancer had spread to his lungs. The diagnosis was osteosarcoma, a type of bone cancer. Unfortunately, this case highlights that osteosarcoma in the kneecap can behave aggressively, similar to other forms of this cancer in dogs. Treatment options would typically include surgery and possibly chemotherapy, but the prognosis can be serious due to the metastasis.

Abstract
A 6-year-old neutered male Rottweiler was examined for a progressive right pelvic limb lameness. In radiographs of the right stifle, there was an osteolytic lesion with irregular new bone formation along the cranial aspect of the patella consistent with an aggressive bone lesion. In thoracic radiographs, there were multiple soft tissue nodular opacities throughout the lung fields, consistent with pulmonary metastases. Microscopically, fine needle aspirate samples from the right patella contained pleomorphic spindle cells with cytologic features of osteosarcoma. The presence of pulmonary metastases at the time of initial diagnosis in the dog described herein suggests that osteosarcoma of the patella has the potential for similar aggressive biologic behavior as that seen in dogs with appendicular osteosarcoma.
