Lymphangioma circumscriptum. A case with deep lymphatic involvement

Lymphangioma circumscriptum is a rare disorder that is localized to the skin. To our knowledge, involvement of deeper lymphatic structures has been reported on only two prior occasions. Our patient had typical lymphangioma circumscriptum of her inner thigh, which was associated with deep lymphatic involvement and enlargement of the extremity. We report this case to alert others to this disease entity.
