Abstract

An 18-month-old male Alaskan malamute was euthanized due to slowly growing mass around the left femur after history of left posterior limb lameness. At necropsy, a firm confluent mass approximately 15cm in diameter was noted surrounding the femur and proximal portion of the tibia/ulna with traumatic ulceration of the overlying skin. On cross sections of the mass, many unencapsulated firm tan coalescing lobules were noted. The neoplasm consisted of closely packed spindle cells with homogenous eosinophilic material (osteoids) between the neoplastic cells. The pulmonary metastasis was confirmed. Based on the gross and histopathologic examinations, the case was diagnosed as juvenile osteosarcoma.
