A case of a venous malformation of the abdominal wall in a 13-year-old boy is hereby presented. This malformation, manifesting as varicosities which were present from infancy caused no disturbances other than cosmetic. Clinical, laboratory and radiological examinations revealed no underlying pathology linked with this malformation. Considering the patient's history, we assumed the varicosities to be sequelae of a deep thrombophlebitis of the right leg in infancy, although a congenital etiology was not excluded. The varicose veins were surgically excised with excellent postoperative results. To the best of our knowledge, no such case was previously reported in literature.
