El presente estudio tuvo por objetivo estudiar estadísticamente las diversas clases de neoplasias que afectan a los caninos de nuestro medio, considerando su origen blastodermico, sexo, raza, edad, localización y grado de malignidad, basados en los diagnósticos histopatológicos por ser el examen de elección mas preciso para su identificación. Para tal fin se analizaron los protocolos de necropsia realizados en caninos que presentaron neoplasias durante el periodo 1990-1994 en el laboratorio de Histopatologia de la Facultad de Medicina Veterinaria de la Universidad Nacional Mayor de San Marcos. Posteriormente, se compararon con estudios anteriores tanto en nuestro medio como en el extranjero.Se encontró que las hembras fueron las mas afectadas (44/76) y los animales entre los 5-12 años presentaron mayor frecuencia (17.1%).En cuanto al origen tisular, las epiteliales estuvieron en primer lugar, siendo los adenocarcinomas mamarios los mas frecuentes (23.6%); seguidos de los hematopoyeticos con el Linfoma maligno como la principal neoplasia (10.5%); luego los conectivos con los fibrosarcomas (5.2%), mientras que los misceláneos representados por el Tumor Venéreo Transmisible (3.9%) ocuparon un cuarto lugar y por ultimo los endoteliales con los hemangiosarcomas como los de mayor frecuencia (3.9%). / The objective of the present work were to statistically study the different types of neoplasms that affect canines of our environment and to consider their blastodermic origin, sex, age, localization and malignancy degree, based on the histopathologic diagnoses, the most accurate exam available for their identification. During 1990-1994 the necropsy protocols were reviewed for canine neoplasms in the Histopathologic laboratory of the School of Veterinary Medicine of San Marcos University. Later, our results were compared with previous studies made in foreign countries. Most of the affected animals (44/76) were female. Animals ranging from 5 to 12 years old also showed a high frequency (17.1%). Most common were the neoplasm of epithelial origin, wherein mammary adenocarcinomas were most frequent (23.6%). Hematopoyetic neoplasms and especially the malignant lymphoma were second most important tumors (10.5%). Among the connective tissue tumors, the fibrosarcoma was most common (5.2%). These were followed by the miscellaneous neoplasms, wherein the Transmissible Venereal Tumor (3.9%) showed the highest frequency. Finally, tumors of endothelial origin had the hemangiosarcoma as the most important neoplasms (3.9%).
