Plain-English summary
Two cats over 10 years old were brought in because their owners noticed non-painful lumps on their legs. X-rays showed abnormal bony growths, and after surgery to remove part of these growths, tests confirmed they had a type of bone cancer called periosteal chondrosarcoma. Although the lumps came back, both cats are still alive and doing well more than 2.5 years later. This shows that surgery can help improve their quality of life and may prevent the need for more drastic measures like amputation.

Abstract
Two cats, both over 10 yr old, were presented for evaluation of non-painful bony proliferations on the appendicular skeleton. These proliferations were identifiable via palpation. Radiographs showed a smooth, proliferative bony lesion of the distal femur (case 1) and tarsus (case 2) with mild soft tissue swelling. Surgical debulking with incomplete resection was performed in each cat. Subsequent histopathology resulted in a diagnosis of periosteal chondrosarcoma (PC). Although both cats have experienced local recurrence, both are still alive more than 2.5 yr after mass debulking. Periosteal chondrosarcoma is a differential diagnosis in proliferative cortical bony lesions near an articular surface in older cats. Partial resection of these masses can lead to an excellent quality of life, and proper diagnosis can avoid amputation or even euthanasia.
