Plain-English summary
A 4-year-old Labrador Retriever was brought to the vet because it had worsening lameness in its left hind leg, particularly around the knee. The vet performed surgery to remove a mass in the joint, which initially looked like a type of cancer but was later identified as pigmented villonodular synovitis, a non-cancerous condition. Unfortunately, nine months later, the dog developed a large tumor in its abdomen that spread to the lungs and liver, leading to the difficult decision to euthanize the pet.

Abstract
A 4-year-old Labrador Retriever was examined because of progressive left hind limb lameness involving the stifle. A villous synovial mass was evacuated by synovectomy. Initially, the macroscopic and histopathologic features suggested a malignant fibrosarcomatous process; however, further histologic studies revealed lesions consistent with pigmented villonodular synovitis. Nine months later, the dog developed a large retroperitoneal tumor, with metastasis to the lungs and liver. The dog was then euthanatized. By histologic and electron microscopic examinations, the tumor was found to be a primitive plasmacytoid lymphoma.
