Cavernous lymphangioma is a benign tumor of lymphatic origin encountering most frequently in young children, and composed of softly fluctuated monolocular or multilocular cystic masses which developed from embryonic outpouching of the venous system. The prevailing site of this tumor Is at the anterolateral neck region particularly posterior triangle, and occasionally axillary, mesentery and spleen etc. Recently, we have experienced one case of left axillary cavernous lymphangioma, which surgically removed successfully and confirmed histopathologically. We want to report one case of left axillary large cavernous lymphangioma with a brief review of the relevant literatures.[KTCS 1979;4:379-382]
