Cavernous lymphangioma in the laryngeal ventricle in an adult patient.

Lymphangiomas of the larynx are quite rare and even rarer in adults. Isolated cavernous lymphangioma in the laryngeal ventricle was diagnosed in a 47-year-old woman. The patient presented with hoarseness with a history of three months. Direct laryngoscopy performed under general anesthesia showed a large, smooth, gray-reddish tumor above the right vocal fold, originating from the right ventricle. The tumor was removed through a micro-laryngoscopic procedure with cold instruments. Histopathologic diagnosis was cavernous lymphangioma. There was no local recurrence a year after the operation.
