Hemangiopericytoma

Laparoscopic resection of intra-abdominal metastasis from intracranial hemangiopericytoma

“…Originally described in 1942 by Stout and Murray [1] , hemangiopericytoma (HPC) is a rare mesenchymal tumor derived from pericytes, the cells of capillary walls and postcapillary venule walls [2] . This tumor type accounts for less than 1% of all sarcomas and can occur at any location in the body, including intra-abdominally [3] . Although most HPC has an indolent course usually, poorly differentiated HPC frequently can have an aggressive tumor biology and a poor prognosis [4–6] .…”
