[Aggressive osteoblastoma of the larynx: case report].

Osteoblastoma agressiva is not often bone tumor, only locally malignant. There are not articles, describing extra skeleton localization. Authors presented case of 45 year old patient, who was treated because of Aggressive Osteoblastoma localized in larynx. Patient has received operation and irradiation treatment. The tumor localization and patients age--more than 35 year are unusual.
