Congenital nasal hemangiopericytoma: intrauterine, intraoperative, and histologic findings.
Hemangiopericytoma is a rare tumor of mesenchymal origin. To date, 91 cases of nasal or paranasal hemangiopericytoma and 59 congenital hemangiopericytomas have been reported in the literature. A congenital hemangiopericytoma arising from the nasal cavity and skull base has not yet been described. We report a case of a male newborn with a highly vascular nasal tumor diagnosed by in utero sonography with three-dimensional surface reconstruction. The tumor extended to the right anterior skull base, the right nasal cavity, and the right side of the nasal pyramid. A complete resection by neodymium:yttrium-aluminum-garnet-potassium titanyl phosphate ("Nd:YAG-KTP") laser was performed on the day of cesarean section at 33 weeks' gestation. The tumor was diagnosed as hemangiopericytoma by histologic and immunohistochemical findings. Postoperative nasal flow, feeding, and sight were unimpaired. At the 9-month follow-up, the infant remained free of disease.
