METASTATIC HEMANGIOPERICYTOMA IN A DOG

A 6-year-old female of the Burgos Pachon breed was referred to the Mur cia Veterinary Teaching Clinic for evaluation of a mass on the left el bow. Ten months earlier, a mass had been removed from the same locatio n, and the diagnosis was hemangiopericytoma. On physical examination t he left axillary lymph node was enlarged. Thoracic radiographs reveale d two nodular densities. The recommended treatment was amputation of t he limb followed by radiotherapy, but the treatment was not performed. A month later, the animal was euthanized and a necropsy performed. Po stmortem examination revealed that the elbow and lung masses had the s ame appearance on the cut section. Histologic findings were consistent with a diagnosis of metastatic hemangiopericytoma.
