Introduction

Vascular neoplasms originate from mesenchymal endothelial tissue. Hemangioma, lymphangioma and scrotal vascular hamartoma are the benign counterparts. Malignant neoplasms are hemangiosarcoma and lymphangiosarcoma.

Objective

To study vascular tumors in canines from CORPAVET casuistic from 2010 to 2014 in Bogotá, Colombia.

Methodology

Databases, history records, and slides of 3561 cases were revised to select vascular neoplasms. Analysis of age, breed, sex, and location of tumor was performed.

Results

We found 143 (7.8%) cases of vascular neoplasms. Seventy (70) were hemangiomas and 73 were hemangiosarcomas. Golden retrievers, Labradors, and mixed breeds were the breeds with the highest frequency of these tumors. The distribution per gender of the vascular neoplasms was higher in males (87–63%) than in females (51–37%). The average age in this presentation was between 9 and 10 years. On the other hand, it is recommended to fill completely the clinical history to have plenty of information to analyse. The use of immunomarkers with diagnostic value (CD31, CD34, von Willebrand Factor (vWF), VEGFR-1, VEGFR-2, GLUT-1) and prognostic value (ki-67 y P53) is desirable.

Conclusions

Vascular neoplasms represent 7.8% of oncopathology casuistic in CORPAVET from 2010 to 2014.
