Resumen
El presente trabajo consistió en una práctica dirigida de 6 meses en el Laboratorio de
Patología Veterinaria de la Escuela de Medicina Veterinaria de la Universidad Nacional y de
un estudio con énfasis en el osteosarcoma apendicular canino.
El desarrollo de la práctica dirigida en el Laboratorio de Patología consistió en la
realización de necropsias tanto de especies menores, mayores como en especies silvestres, en
la observación al microscopio de láminas de histopatología y de citopatología y en la discusión
del diagnóstico final de cada caso con el patólogo a cargo. Cada necropsia incluía la técnica
de disección a emplear, la descripción externa de la carcasa, la observación y descripción de
los hallazgos macroscópicos encontrados, la toma y manejo de las muestras post-morten y la
elaboración de un listado de diagnósticos presuntivos. El análisis microscópico lo realizaba el
patólogo y lo compartía con el estudiante.
El trabajo desarrollado y dirigido especialmente al tema del osteosarcoma apendicular
canino (neoplasia maligna más frecuente de los miembros apendiculares del perro), se dividió
en dos estudios, uno retrospectivo y otro prospectivo. En el estudio retrospectivo, se tomaron
todos los casos archivados de OS apendicular canino, diagnosticados desde 1992 hasta el año
2004 en el Laboratorio de Patología. Con respecto al estudio prospectivo, se tomaron 2 casos
con OS apendicular remitidos al Laboratorio durante la práctica. Con ambos estudios se
investigaron las razas, la edad, la incidencia, el sexo, los sitios anatómicos, los signos clínicos
y hallazgos patológicos más frecuentes de Osteosarcoma apendicular en los perros de Costa
Rica.
This was a six months practice in the Veterinarian Pathology Laboratory of the Veterinarian School of the National University, Costa Rica; and one researching with its emphasis in the canine appendicular osteosarcoma. The development of the practice in the Pathology Lab was about the performance of necropsy in small animals, as well as in large and wild animals, the observation under the microscope of the histopathology and citopathology samples and the discussion of the final diagnosis of every case with the pathologist in charged. Every necropsy included the dissection technique to be used, the outer description of the carcass, the observation and description of the macroscopic findings, the way of taking and handling the post-morten samples and the elaboration of a presumptive diagnostic list. The microscopic analysis was performed by the pathologist, assisted by the student. This research was developed and especially focused on the canine appendicular osteosarcoma (the most frequent malignant neoplasia in the dogs’ appendicular extremities). It was divided in two studies; one retrospective and the other one prospective. Within the retrospective, all the canine OS appendicular filed cases were taken, diagnosed since 1992 till 2004 in the Pathology Lab. Regarding to the prospective study, two cases with appendicular OS were taking, both referred to the Lab during the practice. Breed, age, incidence, sex, anatomic sites, clinic symptoms, and the most frequent pathologic findings of the appendicular osteosarcoma in Costa Rica’s dogs were investigated in both studies.
