Background: Canine hemangiosarcoma is a malignant neoplasm of endothelial cells. Such tumor has most commonly its primary location in the spleen, right atrium, subcutaneous tissue and liver. In general, metastases occur in the liver, omentum, mesentery and lung. The nervous system may be a metastasis site, but with rare spinal cord involvement. This paper aims at the description of canine cutaneous hemangiosarcoma with metastasis to the central nervous system.Case: A dog presented history of skin neoplasia. The patient underwent physical examination, which detected an exophytic tumor in the foreskin. Needle aspiration of the lesion was carried out, suggesting the presence of malignant neoplasm of mesenchymal origin. So, the lesion surgical excision was the option. Before the procedure, complementary preoperative examinations of the patient were required. Those corresponded to chest radiographs, abdominal ultrasound, complete blood count, serum urea, creatinine, alanine aminotransferase, aspartate aminotransferase and total protein. The image diagnostic of the thoracic and abdominal cavities showed no noteworthy changes. The hematology and serum biochemistry were normal. The tumor obtained during surgery was sent for histopathological analysis, whose diagnosis corresponded to hemangiosarcoma. Chemotherapy treatment was not possible in the animal. Nine months after the surgery, a
