Hemangiomas of the nasal septum and paranasal sinuses.

Hemangiomas of the nasal septum and paranasal sinuses are rare; only 62 cases of septal hemangiomas and 32 cases of maxillary sinus/maxilla hemangiomas have been reported in the English literature. Hemangiomas should be considered in the differential diagnosis of any nasal mass lesion because biopsy may result in profuse bleeding and even death. We report the clinical presentation, differential diagnosis, etiology, and histologic appearance of paranasal sinus hemangiomas occurring in four of our patients.
