Fetal hemangiopericytoma with an associated cerebral anomaly

Multifocal Congenital Hemangiopericytoma

Congenital hemangiopericytoma (HPC) is a rare mesenchymal tumor with less aggressive behavior and a more favorable prognosis than similar tumors in adults. Multifocal presentation is even less common than isolated HPC and hence its clinical and histologic recognition may be challenging. A newborn infant with multifocal congenital HPC causing severe deformity but with a favorable outcome after chemotherapy and surgical removal is reported.

Infantile Hemangiopericytoma

Infantile hemangiopericytoma (HPC) is an uncommon tumor that arises from Zimmermann pericytes. It occurs before 12 months of age and may be present at birth, so intrauterine detection by sonography is possible. These solid, vascular neoplasms typically occur in the subcutaneous tissues of the head and neck and follow a benign course. Diagnosis of infantile HPC must be made by histology, and surgical resection is the most common method of treatment.
