Abstract:
The pathological features of a mass in the back skin region of an 8-year-old castrated male dog are described herein. The cut section of the tumor was white to tan with a soft multilobulated mass containing hemorrhagic and necrotic foci and a mucinous-like composition. Microscopically, the tumor was composed of a mixture of lipocytes, lipoblasts, spindle cells and stellate cells and had a myxoid background. Oil red O staining revealed that the cytoplasm of neoplastic cells contained large numbers of lipid droplets. Immunohistochemically, tumor cells were positive for vimentin and S-100 protein. The skin mass was diagnosed as myxoid liposarcoma.
