Plain-English summary

A 7-year-old dog was diagnosed with a high-grade surface osteosarcoma, a type of aggressive bone cancer, in its front leg. Although X-rays showed no bone damage, there was increased soft tissue swelling around the area. This cancer was identified due to its early spread to other parts of the body and specific tissue tests. Unlike other types of surface osteosarcomas in dogs, which are usually less aggressive, this case resembled a more serious form seen in humans. Treatment options would typically include surgery and possibly chemotherapy, but the specific outcome for this dog isn't detailed.

Abstract

A case of a high-grade surface osteosarcoma in the thoracic limb of a dog is reported. Radiographically, there was no bone involvement but there was increased soft tissue opacity. An aggressive osteosarcoma was diagnosed on the basis of early metastatic disease and histopathological examination. Previously reported surface osteosarcomas in the dog have been periosteal and parosteal osteosarcomas which are generally considered to have a low to intermediate biological activity. The tumour described here had radiographical, gross pathological, histopathological and biological features consistent with human high-grade surface osteosarcoma. The characteristics of surface osteosarcomas are briefly reviewed.
