A13-year-old spayed female dog had a mass in the left auricle. Grossly, connection between the mass and original auricular cartilage was not recognized. The mass was unencapsulated and contained multiple islands of mature hyaline cartilage and neoplastic adipocytes. The neoplastic cells comprised predominant mature adipocytes, scattered lipoblasts and irregular round to spindle cells with moderate atypia. The atypical cells occasionally had lipid droplets. A diagnosis of well-differentiated liposarcoma (WDL) with chondroid metaplasia was made. This is the first report for liposarcoma with chondroid metaplasia in the auricle of domestic animals.
