Objective: Lymphangiomas are rare congenital malformations commonly seen in children. Its occurrence in adults is uncommon with very scarce reports in the literature. It mainly occurs in infants or children younger than two years of age. We report these cases to emphasize the need to consider cystic lymphangiomas in differential diagnosis of neck masses in adults.

Case Reports: We describe two cases in adults, one a 27-year-old man and the other a 59-year-old male. The former presented with recurrent neck mass for 5 years, and the latter presented with asymptomatic neck mass of a short duration. Both were not associated with any pain, discoloration, discharge or sudden increase in size.

Conclusion: The awareness of occurrence of cystic lymphangioma in adults is important for its proper management which includes complete surgical removal, to prevent recurrence.
