Purpose:
To present a case of Haemangiopericytoma (HPC), a rare neopalsm which originates from the vascular pericytes. HPC occurs most commonly in adults. Only 5-10% of cases occur in children. Congenital orbital HPC is generally unknown in the field of ophthalmology.
Material And Methods:
A case of congenital, large exophthalmus is reported in a 1 day old male neonate. Imaging studies demonstrated a vascular, orbital mass involving skull base and cranial fossa.
Results:
The diagnosis of HPC was established after histological exmination. Lesion did not qualify to surgical resection. The child was treated with chemotherapy for 10 months and a great regression of tumor was noted. There was no tumor recurrence during 4 years of a follow up.
Conclusions:
Chemotherapy may have a significant role in the treatment of infants with nonoperative malignant hemangiopericytoma.
