[Capillary hemangioma of the ethmoid sinus. Case report and review of the literature].

We report the rare observation of a 38-year-old man diagnosed with capillary hemangioma exclusively involving the ethmoid sinus. Complete resection was obtained via ethmoid endoscopy combined with an intracranial approach. Capillary hemangioma is a rare and benign vascular tumor in adults primarily developing in the skin and subcutaneous tissues of the head and neck, and/or within oral and nasal cavities. No hemangioma exclusively involving the ethmoid sinus has been previously reported. Complete resection is the treatment of choice, providing a favorable prognosis with low risk of recurrence.
