A 73-year-old woman developed an allergic contact dermatitis of the feet and legs 24 days following lymphangiography. Dermatitis was accompanied by a generalized urticarial reaction. Intracutaneous skin testing was positive to Evans blue dye, used as a lymphatic marker, but negative to Ethiodol, an iodine-containing contrast medium. Soft tissue x-rays x-rays revealed extravasated Ethiodol in the left leg but not in the right, while dermatitis occurred on both legs. This finding, combined with the positive skin test to Evans blue, stress the importance of testing with both agents when dermatitis develops following lymphangiography. Intracutaneous rather than epicutaneous testing is the indicated route and may be related to the route of sensitization.
一名73岁女性在淋巴管造影术后24天出现足部和腿部过敏性接触性皮炎。皮炎伴有全身性荨麻疹反应。皮内皮肤试验对用作淋巴标记物的伊文思蓝染料呈阳性，但对含碘造影剂乙碘油呈阴性。软组织X线显示左腿有乙碘油外渗，右腿没有，而双腿均出现皮炎。这一发现，结合对伊文思蓝的阳性皮肤试验，强调了淋巴管造影术后发生皮炎时对两种试剂都进行检测的重要性。皮内试验而非表皮试验是指定的检测途径，这可能与致敏途径有关。
