Two Cases with a Large Cavernous Hemangioma of the Larynx and Hypopharynx.

Two patients with a large cavernous hemangioma are reported. One was an 11-year-oldmale complaining of a slowly growing cervical mass without tenderness. Indirect laryngeal examination showed multiple dark purple nodules on the right pyriform sinus and larynx. MRI examination revealed a tumor located on the larynx, the hypopharynx and the right neck. The mass was removed surgically with a right cervical incision. Two weeks later, the residual hemangioma of the larynx was vaporized by a CO2 laser through a direct laryngoscope.The second patient, a 55-year-old female, complained of throat discomfort. An irregular-surfaced mass was found by indirect laryngoscopy. The tumor occupied the left pyriform sinus, aryglottic fold, false cord and epiglottis. It was found to have deeply invaded the left vocal cord under MRI examination. The tumor was removed by a lateral pharyngotomy and laryngofissure.
