Venous ulcers cause considerable morbidity. A 45-year-old man reported with non healing ulcer since 15 years. Patch tests revealed multiple sensitivity. Infection was first controlled with antibiotics and antiseptics. Dressing with modified Unna's boot made with zinc oxide 40% and glycerine paste 60% resulted in formation of healthy granulation tissue. Pinch grafting was subsequently done to promote epithelization. We recommend the use of Unna's paste instead of more expensive synthetic and occlusive and semi occlusive dressing to promote granulation tissue and pinch grafting after bed is ready to hasten epithelization.
