Summary:A 7-year-old spayed female domestic shorthair cat was referred for evaluation of a localized growing mass on the left flank. Cytologic and histologic findings suggested that the mass was an extraskeletal osteosarcoma. Radiography failed to reveal any association between the lesion and the axial or appendicular skeleton. Because of the large size of the tumor, the cat was treated with carboplatin prior to and after surgery (hemipelvectomy) to ensure that surgical margins were free of neoplastic cells and to prevent systemic dissemination of malignant cells. The tumor has not recurred during a 2-year follow-up period.
