An osteosarcoma developed in the tarsal joint region involving the distal tibia of a domestic rabbit (Oryctolagus cuniculus). Micrometastases were present in the lungs. Histologically the tumor was composed of ovoid to short-spindle cells with abundant giant cells, producing irregular islands of osteoids. The tumor cells were immunopositive with antiosteocalcin monoclonal antibody, consistent with their derivation from osteoblasts. According to review of 10 published cases, productive osteoblasic osteosarcoma is the most common bone tumor in rabbits, with half of all cases developing in the skull or facial bones.
