Canine hemangiosarcoma: review

Abstract

Canine Hemangiosarcoma is a malignant neoplasm of blood vessel endothelial cells, highly metastatic when in its visceral form, and may also manifest as a primary cutaneous form. The canine species is described as being the most affected. Males aged between 10 and 12 years are more predisposed to the development of Hemangiosarcoma (HSA). The clinical manifestation of the disease is nonspecific and varies according to the location of the primary site or metástases. The definitive diagnosis occurs through histopathology by biopsy of the tumor. The therapy is given by surgical excision and oncologic therapeutic protocols. The prognosis is considered reserved, depending on which phase the disease was diagnosed. This literature review aims to clarify and contribute to the knowledge of the pathology, through the evaluation of affected organs and systems, clinical signs as well as the presentation of available diagnoses and treatments.
