"Bleeding polyp" of the nasal septum: an uncommon lesion in adults.

Inflammatory hemangioma of the nasal septum, known as "bleeding polyp," is an uncommon lesion in adults. We report the case of a 20-year-old woman who presented with left nasal hemangioma revealed by unilateral epistaxis and obstruction. The patient had a medical history of septoplasty performed 5 years earlier. This benign tumor can be spontaneous or posttraumatic and occurs in young postpubertal adults or patients over 40 years of age, without a sex preponderance. The site of origin is most frequently the cartilaginous septum. The appearance and clinical signs often mimic malignancy, and a biopsy for histologic confirmation of the diagnosis is crucial. The capillary hemangioma is more frequently observed than the cavernous type. This tumor does not present spontaneous involution, and treatment is based on a surgical excision including the mucosa and the underlying perichondrium, after computed tomographic and/or nuclear magnetic resonance examination.
