Lymphangioma(or cystic hygroma) of the chest wall is rare case. We experienced one such case in a 16-year-old girl who complained of a large recurrent mass on her right upper post erolateral chest wall which had developed several years ago. The diagnosis was made following a physical examination, chest magnetic resonance imaging(MRI), and radio isotope (RI) lymphangiogrphy and was confirmed by a histopathological examination. We performed total excision of the lesion followed by a repeated sclerosing therapy with intralesional injection of Vibramycin.
