title: Multifocal Congenital Hemangiopericytoma.
abstract: 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.
