Leiomyosarcoma in a Canine Right Thigh Muscle

Abstract

We excised a tumor from the inside of the right thigh of a five-year-old, male, Golden Retriever lame in the right pelvis. Seven days after surgery, normal walking and locomotion had been restored. Four weeks later, however, the tumor recurred, necessitating a second operation. This operation was only incompletely performed because the neoplasm had spread widely around the femur and the femoral artery and vein. The dog died in the third week after second surgery. Histopathological findings from collected samples led to a diagnosis of leiomyosarcoma. Metastasis had reached the lungs, liver, heart, diaphragm, kidneys, and prostate gland.
