Laryngeal Cavernous Lymphangioma in an Adult Patient

Introduction: lymphangiomas are uncommon congenital lesions of the lymphatic system, and most of them are detected by the second year of life. although head and neck region is the most common location, laryngeal involvement isextremely rare, and the literature is largely limited to few case reports. case report: a 51-year-old male patient was admitted to the hospital with clinical history of hoarseness. performed direct laryngoscopy revealed a pedunculated cystic mass located in the right ventricle of the larynx. the mass was totally excised, and the case was reported as cavernous lymphangioma. conclusion: isolated laryngeal lymphangioma is extremely rare in adults. the other benign lesions or inflammatory processes in this region can mimic laryngeal lymphangioma. therefore, this entity should be kept in mind in differential diagnosis especially in adults, to avoid overtreatment.
