Congenital Hemangiopericytoma in the Retroperitoneum: A Case Report in a Newborn / 대한주산의학회잡지

Hemangiopericytoma is a rare vascular tumor that usually occurs in adults. The tumor is believed to originate from pericytes that are closely related to the capillary walls. Congenital hemangiopericytoma is a more rare disease that occurs in approximately 0.03% of all heamngiopericytomas. Herein, we describe a 1-month-old male newborn with huge congenital hemangiopericytoma in the retroperitoneum that exhibited a typical morphological vascular pattern.
