Adult Laryngeal Ossified Hemangioma: Difficulties in Differential Diagnosis

Adult laryngeal hemangiomas are uncommon and often poorly symptomatic. The authors describe a laryngeal hemangioma with acute airway obstruction and radiologic findings suggesting a chondrosarcoma-like neoplasm, while pathologic features were consistent with an ossified hemangioma. The presence of fields of bone metaplasia into a classical cavernous hemangioma is an unusual phenomenon which, to our knowledge, was never previously described in the larynx. Difficulties concerning the differential diagnosis and modality of treatment are also discussed.
