Localized Primary Hepatic Hemangiosarcoma in a Dog Surviving for a Long Time after Surgical Treatment and Chemotherapy

Abstract

A female Shiba dog, ten years and eight months old, was referred to our hospital for further examinations and treatment. Erythrocytosis and the presence of a liver mass had been diagnosed at a previous clinic. Hematology showed erythrocytosis at our hospital as well. As the single mass in the right lateral lobe was confirmed by ultrasonography and computed tomography, the relevant lobe was removed completely. Histopathologically the mass was diagnosed as a hemangiosarcoma. Beginning ten days after surgery, the dog was given 30 mg/m² of doxorubicin every three weeks, six times in total. Until now the dog has been in good condition without medication for four years. Erythrocytosis disappeared after surgery.
