Lipossarcoma em cão: relato de dois casos

This work aims to describe the clinical and anatomopathological findings of two cases of liposarcoma diagnosed in the subcutaneous and abdominal cavity of dogs. In both cases, the tumoral masses were surgically removed and samples were submitted for histopathological analyses. Microscopic examination of each case revealed a highly cellular, pleomorphic neoplasm with round or polygonal fat cells. The nuclei was elongate or splindle-shape (subcutaneous liposarcoma) and round or ovoid (abdominal liposarcoma), contained margined chromatin, and prominent nucleolus. Cytoplasmic vacuoles that stained positively with Sudan IV varied highly in size
