Microcystic lymphatic malformation (also known as lymphangioma circumscriptum) presents as a collection of poorly defined, small lymphatic channels that appear as clear or hemorrhagic vesicles. Lymphangioma circumscriptum can evolve over time with various distributions and colors of the vesicles. The lesions can present clinically anywhere on the body but have a predilection for the proximal limbs, chest, and the mouth. Bleeding and crusting of the lesions can complicate the course. Rarely, infection may occur.
