Fernando Miranda Monroy Multidisciplinaria (Ciencias Naturales y Exactas) Perro Osteosarcoma paraosteal Tumores primarios de hueso El osteosarcoma paraosteal constituye una neoplasia primaria de hueso, caracterizada por desarrollarse en la superficie ósea; está compuesta por tejido fibroso, óseo y cartilaginoso bien diferenciado pero con características de malignidad. El caso se presentó en un perro Pastor Alemán, macho, de 8 años de edad, diagnosticado por punción con aguja delgada y estudio radiográfico, y confirmado por estudio histológico. 1999 artículo científico 0301-5092 https://www.redalyc.org/articulo.oa?id=42330116 es http://www.redalyc.org/revista.oa?id=423 Veterinaria México application/pdf Universidad Nacional Autónoma de México Veterinaria México (México) Num.1 Vol.30
