title: Aneurysmal bone cyst of the larynx.
abstract: Aneurysmal bone cyst is a rare lesion of the head and neck, and the mandible and maxilla are the most common sites of occurrence. To the authors' knowledge, two cases of aneurysmal bone cyst of the larynx described here are the first to be reported. Although the exact pathogenesis of this lesion is unknown, several theories of its origin are discussed. Complete surgical excision is the treatment of choice. Radiation therapy for this benign lesion is not indicated because of a possible association with the development of sarcoma. Histologic misdiagnosis of carcinoma or sarcoma of the larynx leading to unnecessary radical surgery is a risk and should be avoided by obtaining expert pathologic consultation.
