Congenital hemangiopericytoma in a neonate.
Hemangiopericytoma is a rare malignant vascular tumor that usually occurs in adults. The occurrence of these tumors in infants, known as congenital or infantile hemangiopericytoma, is even rarer and their behavior may be more benign than the adult type. We describe a 1-day-old female neonate with congenital hemangiopericytoma, presenting with a right inguinal mass at birth. At the time of surgery, lymphangioma was suspected because of its appearance, fluid-filled multicystic content, and the high incidence of this disease in pediatric patients. Tumor excision was performed and hemangiopericytoma was diagnosed by histology. There was no tumor recurrence during 12 months of follow-up.
