Malignant transformation in a laryngeal hemangioma.
Laryngeal angiosarcoma is uncommon, with only 19 previously reported cases. Malignant transformation in nonirradiated hemangiomas is extremely rare, with only five equivocal cases reported, all of which occurred in the skin. We report the first documented case of malignant transformation in a laryngeal hemangioma, and review the literature.
