title: Nasal angioma with osseous metaplasia.
abstract: Nasal angiomas are rare. We report a case showing osseous metaplasia and discuss pathogenesis hypotheses. A 41-year-old woman presented with a right lateronasal firm, immobile mass, and interfering with glass wearing. The computed tomography scan imaging was suggestive of chondroma while the magnetic resonance imaging showed on T1-weighted images nodule isosignal, on T2-weighted images hypersignal, and intense enhancement after contrast substance injection. The lesion was surgically resected. Histological examination revealed a 0.8 cm angioma with multifocal osseous metaplasia. The diagnosis of nasal angiomas with extensive osseous metaplasia is difficult requiring microscopic examination. Conservative surgery is the treatment of choice even at an early stage due to the limited effectiveness of embolization or drugs on the osseous component.
