Lymphangioma circumscriptum is a benign lymphatic ectasia with two components: A clinically apparent dermal vascular component and a not so apparent deep subcutaneous cisternal structure.[ 3 ] Although it is characterized by translucent, pink-red vesicle bundles with thin membranes sometimes filled with blood, the vesicles have clear edges, and can be scattered or in groups.[ 4 ] For the differential diagnosis of lymphangioma circumscriptum, lymphangiectasia, hemangioma, verruca, molluscum contagiosum, angiokeratoma, and lymphangioendothelioma should be considered.[ 2 ] The risk of malignant conversion is very low for lymphangioma circumscriptum.
