Osteosarcoma apendicular en canino de raza criolla.

Abstract

Osteosarcoma (OSA) is considered the most common primary bone neoplasia in canines, characterized by the formation of osteoid tissue, fast growth and metastasis formation. This case report describes a canine patient with a left anterior limb amputation due to an accident and an abnormal tissue growth at the amputation site. The morphological location and dimensions of a bone neoplasm were determined, and by means of radiographic examinations the absence of me tastases was proven. By means of surgical intervention, the lesion was removed and by means of histopathological and natomo-pathological study, it was possible to confirm as definitive diagno sis an appendicular osteosarcoma. The surgical wound cicatrization was fast and without com plications, and during the three-month period after the surgery, the patient did not show recu rrence or metastasis to other organs, demonstrating success in the established treatment.
