Retroperitoneal extraskeletal osteosarcoma in a dog: a case report

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...

Serum biochemistry results showed alterations in blood urea nitrogen, serum alkaline phosphatase, and creatinine.

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.Universidad Nacional, Costa Rica2016-07-11info:eu-repo/semantics/publishedVersionartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlhttps://www.revistas.una.ac.cr/index.php/veterinaria/article/view/849110.15359/rcv.34-1.5Ciencias Veterinarias; Vol. 34 No. 1 (2016): Ciencias Veterinarias (Enero-Junio); 55-63Ciencias veterinarias; Vol. 34 Núm. 1 (2016): Ciencias Veterinarias (Enero-Junio); 55-632215-45070250-5649reponame:Portal de Revistas UNAinstname:Universidad Nacional de Costa Ricainstacron:UNAspahttps://www.revistas.una.ac.cr/index.php/veterinaria/article/view/8491/9611https://www.revistas.una.ac.cr/index.php/veterinaria/article/view/8491/9708Derechos de autor 2016 Revista Ciencias Veterinariasacceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2019-08-27T15:19:54Zoai:ojs.www.una.ac.cr:article/8491Portal de revistashttp://revistas.una.ac.cr/Universidadhttp://www.una.ac.crhttps://revistas.una.ac.cr/index.php/index/oaiandrea.mora.campos@una.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2019-08-27T15:19:54Portal de Revistas UNA - Universidad Nacional de Costa Ricafalse
