A Case of Laryngeal Cavernous Lymphangioma / 대한이비인후과학회지

ABSTRACT

Lymphangiomas are rare congenital lesions of the lymphatic system, and about 90% of them are diagnosed within 2 years of age. The most common site is the head and neck region, where approximately 75% of all lymphangiomas occur. However, the laryngeal involvement of lymphangioma is uncommon and most of these cases are direct invasion from the neck. Isolated lymphangioma of the larynx is extremely rare and only a few cases have been reported in the English literature. In our case, correct preoperative diagnosis was difficult due to the rarity of the isolated laryngeal lymphangioma and its resemblance to epiglottic cyst. Careful laryngeal endoscopic examination is needed and imaging study such as CT or MRI may be helpful.
