Infantile Hemangiopericytoma: Two Cases Report and Literature Review

Abstract

Hemangiopericytoma is a rare vascular tumour of infants. Although generally considered to be benign, local recurrence and metastases can occur. Herein, we report on two full term girls, delivered with lumbosacral swelling and left thigh swelling respectively. Complete surgical excision with safety margins was performed for each lesion. Histologic examination of both lesions showed picture of infantile hemangiopericytoma. There is no evidence of local recurrence or distant metastasis during last 20 and 17 months for 1 st case and 2 nd case respectively. In conclusion; most infantile hemangiopericytoma follow a benign course. Rarely these tumours behave aggressively with local infiltration, recurrences and even distant metastases. Careful follow up is therefore essential.

Giant Neck Hemangiopericytoma Detected on Fetal Magnetic Resonance Imaging

“…Although the tumor is thought to be more commonly located in the neck and face, it may be encountered in a wide variety of other locations from meninges to lumbosacral and thigh regions. 4,5 Fetal MRI diagnosis of infantile hemangiopericytoma has been reported previously. [6][7][8][9] In two instances, there were multiple lesions located in the head and retroperitoneum.…”

Benigne Weichteiltumoren des Kopf-Hals-Bereiches im Kindes- und Jugendalter

“…Wie bei Hämangiomen wurden Spontanremissionen beschrieben. Trotz benigner Kategorisierung kommen lokale Destruktionen bei anhaltender Wachstumstendenz vor (1). Die chirurgische Exzision mit Sicherheitsabstand ist daher die Therapie der Wahl.…”
