Cystic lymphangioma of the neck in an adult: A case report.

Lymphangiomas are rare congenital malformations commonly seen in children. Its occurrence in adults is uncommon. The treatment of choice is complete surgical removal; however, the tumour tends to spread along vital structures therefore sometimes complete surgical removal is impossible. We describe the clinical and pathological features of cystic lymphangioma diagnosed in an adult with lateral neck mass. Clinical examination, ultrasonography, CT and fine-needle aspiration cytology were performed with complete resection. We report this case to emphasize the need to consider cystic lymphangioma in the differential diagnosis of lateral neck masses in adults, together with adequate imaging and cytological studies to corroborate the preoperative diagnosis.
