Abstract

The prevailing discipline notes that primary pulmonary angiosarcoma is an extremely rare malignant tumor with almost grave prognosis when presented in a dog. No cases have been reported earlier as occurring in dogs. This is the first time we are reporting a case of primary lung angiosarcoma in a 12-year-old Yorkshire terrier breed dog, that will explore the clinical as well as histopathological features of the tumor as noted in a dog. In this case, radiography revealed a well-defined large soft tissue mass in the caudo-dorsal lung field across the left hemi-thorax. After necropsy, it is noted that the lung was found to have the blood-filled nodular lesions on its surface, as determined with no such lesions on other organs. Upon the histological examination, it showed the presence of an extensive necrotic hemorrhage with anastomosing vascular space. Later, the immunohistochemistry showed strongly positive CD31 cells confirming the endothelial origin of the tumor. This is the first report of canine primary lung angiosarcoma in the Republic of Korea.
