A patient with allergic contact dermatitis caused by hexavalent chromium plating on a cellular phone has already been reported.
This study described the clinical characteristics and results of patch tests in 8 patients with contact dermatitis possibly caused by handling a cellular phone.
The 8 patients were 4 males and 4 females aged from 14 to 54 years. They each noticed skin eruptions after 9-25 days of using a cellular phone. All patients had erythema, and 7 had papules on the hemilateral auricle or in the preauricular region. Three of 8 patients had a history of metal allergy. Chromate, aluminium and acrylnitrile-butadiene-styrene copolymer were used as plating on the cellular phones used by these patients.
Closed patch tests and photopatch tests were performed using metal standard antigens.
The patch test was positive for 0.5, 0.1 and 0.05% potassium dichromate in all 8 patients. The photopatch test showed the same results. One patient was positive for 2% cobalt chloride and one for 5% nickel sulfate.
It is important to consider the possibility of contact dermatitis due to a cellular phone, possibly caused by chromate, when the patients have erythema and papules on the hemilateral auricle or in the preauricular region.
已有报道一名因手机六价铬镀层导致过敏性接触性皮炎的患者。
本研究描述了8例可能因使用手机引起接触性皮炎患者的临床特征及斑贴试验结果。
8例患者中，男性4例，女性4例，年龄14至54岁。他们在使用手机9至25天后均出现皮肤疹。所有患者均有红斑，7例在单侧耳廓或耳前区域有丘疹。8例患者中有3例有金属过敏史。这些患者使用的手机上镀有铬酸盐、铝和丙烯腈-丁二烯-苯乙烯共聚物。
使用金属标准抗原进行封闭斑贴试验和光斑贴试验。
所有8例患者对0.5%、0.1%和0.05%重铬酸钾的斑贴试验均为阳性。光斑贴试验结果相同。1例患者对2%氯化钴呈阳性，1例对5%硫酸镍呈阳性。
当患者单侧耳廓或耳前区域出现红斑和丘疹时，应考虑手机引起接触性皮炎的可能性，可能是由铬酸盐所致。
