title: Vascular hamartoma of the paranasal sinuses: report of 3 rare cases and a short review of the literature.
abstract: The paranasal sinuses are an extremely unusual location for a vascular hamartoma. As far as we know, only 1 such case has been previously reported in the English-language literature. We report 3 new cases of vascular hamartoma of the paranasal sinuses, which occurred in a 20-year-old woman and in 2 men aged 36 and 45 years. Radiologically, the lesion in the woman was confined to the sinuses, while evidence of intraorbital extension was seen in the 2 men. No intracranial extension was seen in any patient. The diagnosis was confirmed by histopathologic examination of the excised lesions. All 3 patients were alive without recurrence at 12 to 24 months of follow-up.
