Abstract

Canine osteosarcoma is the most common bone tumor in dog and is characterized by locally aggressive and highly metastatic behavior [1]. Generally malignant tumors meta stasizes by hematogenious routes and rarely through lymphatic pathway, and the lymph node is uncommon metastatic site [2,3]. In this case, the patient has a typical osteosarcoma on his proximal humerus that is the common form of canine OS [4,5]. But the tumor made severe metastatic form to the right axillary lymph node which has a diffuse contribution of osteoid matrix all of the tissue. So, the case is the valuable topic for evaluate the correlation of metastasis to lymph node which is near the primary tumor region and pro gnosis of canine appendicular osteosarcoma. (omitted)
