Abstract
Hepatic small vessel neoplasm (HSVN) is a recently described vascular neoplasm of the adult liver. The neoplastic cells are positive for markers of vascular lineage (CD31, CD34, FLI-1). The distinctive morphology and infiltrative borders separate HSVN from benign vascular tumors such as cavernous hemangioma, while lack of atypical morphologic features, low to absent mitotic activity and low proliferation index distinguish it from malignant vascular tumors such as epithelioid hemangioendothelioma and angiosarcoma. Due to its infiltrative nature and lack of adequate follow-up information, the benign versus low grade nature of this tumor is currently uncertain. We present a patient with resected HSVN involving all but the right posterior section of the liver, making this case the largest reported in the current literature.
