닥스훈트의 원발성 비장 혈관주위세포종 증례

초록

A 7-year-old, castrated male dachshund dog with tumor of the spleen portion was referred to the Kangwon National University. The tumor removed surgically and tumor size was 6∼7 cm. Histopathologically, this neoplasm was the presence of perivascular whorls of fusiform cells. The cells also arranged in interlacing bundles or storiform patterns. And this neoplasm consisted of spindle cells that often formed distinct whorls around a central capillary. Immunohistochemical analysis revealed multifocally immunoreactivity for a-smooth muscle actin, whereas not immunoreactive for desmin, S-100, von Willebrand factor. On the base of the histological and immunohistochemical results, this neoplasm was diagnosed as a canine hemangiopericytoma.
