VETERINARIA84912019-08-27T15:19:54Z Retroperitoneal extraskeletal osteosarcoma in a dog: a case report Osteosarcoma extraesquelético retroperitoneal en un perro: reporte de un caso Piedra-Mora, César Barrantes-Murillo, Daniel Alfaro-Alarcón, Alejandro osteosarcoma extraesquelético retroperitoneo perro Extraskeletal osteosarcoma retroperitoneum dog A 15-year-old not neutered mixed-breed dog was presented with hyporexia, constipation, lethargy and abdominal pain. An intra abdominal mass was identified during the physical examination. Mild normocytic and normochromic anemia and leukocytosis due to neutrophilia were detected in the complete blood count. Serum biochemistry results showed alterations in blood urea nitrogen, serum alkaline phosphatase, and creatinine. A splenic nodule was detected during the ultrasonographic examination, and radiographic findings showed a radiopaque area in the abdomen near the lumbar vertebrae. An exploratory laparotomy was done, and two retroperitoneal masses were found. Due to the difficult surgical approach euthanasia was elected. Histopathological and immunohistochemical evaluation of tissues was performed and the diagnosis of extraskeletal osteosarcoma was made. Extraskeletal osteosarcoma is an infrequent malign mesenchymal tumor without primary involvement of bone tissue or periosteum. Seldom has the retroperitoneal localization of this tumor been reported. Se presentó un perro, de raza mixta, no castrado, 15 años de edad, con hiporexia, constipación, letargia y dolor abdominal. En el examen físico, se identificó una masa intraabdominal. Las pruebas hematológicas evidenciaron anemia leve, normocítica y normocrómica y leucocitosis a causa de neutrofilia. Los resultados de bioquímica sérica mostraron alteraciones del nitrógeno ureico sanguíneo, fosfatasa alcalina sérica y creatinina. En el ultrasonido, se detectó un nódulo en bazo. Las radiografías evidenciaron un área radiopaca en abdomen, cerca de las vértebras lumbares. Se realizó laparotomía exploratoria y se encontró dos masas retroperitoneales. Se realizó la eutanasia del paciente, debido al difícil abordaje quirúrgico. El análisis histopatológico e inmunohistoquímico de las masas fue concluyente de un osteosarcoma extraesquelético. Los osteosarcomas extraesqueléticos son tumores malignos, de origen mesenquimal infrecuentes, sin involucramiento primario de tejido óseo o periostio. La localización retroperitoneal de estos tumores pocas veces ha sido reportada.
