Microcystic lymphatic malformation (lymphangioma circumscriptum) is the most common cutaneous lymphatic malformation, consisting of abnormal, dilated, and tortuous lymphatic vessels in the dermis and subcutaneous tissue. It is due to irregular vessel contraction with subsequent dilatation and fluid build-up that manifests clinically as multiple, grouped, small macroscopic superficial vesicles filled with clear or serosanguineous fluid. The lesions are frequently located over proximal limbs, axillae and chest but may occur on any part of the body. We report a case of lymphangioma circumscriptumin a four-year-old child, partially treated with fractional carbon dioxide laser ablation under local anesthesia. Most of the lesions resolved but the treated areas healed with hypertrophic scarring after one month, which was cosmetically acceptable. Compared to surgical excision, carbon dioxide laser ablation may provide less chances of contractures especially in areas overlying a joint and may be considered as an alternative to more invasive procedures.
