Hemangiopericytoma of the Nasolabial Fold Area: A Case Report

Hemangiopericytoma is uncommon mesenchymal tumor that represents 1% of all vascular neoplasms. Approximately 15 to 30% of hemangiopericytoma occur in the head and neck region, of which the sinonasal tract is the most common site. The lesions that manifest as nasolabial fold fullness are rare, and any lesion appearing as a well-circumscribed, soft mass occurring beneath the alar base should be evaluated as a possible nasolabial cyst. We report the unusual case of a nasolabial mass histologically proven to be hemangiopericytoma with clinical manifestations that were similar to a nasolabial cyst. The postoperative course was uneventful, and follow-up during 28 months revealed no locorégional recurrence. (J Clinical Otolaryngol 2012;23:289–291)
