Eczema-like psoriasiform dermatitis has been described as a complication after Brazilian keratin treatment, with the presence of perifollicular scale resembling the outer skin of an onion bulb reported as a characteristic trichoscopic feature. To date, no treatment for this condition has been communicated.
A retrospective study was conducted on patients diagnosed with eczema-like psoriasiform dermatitis. Clinical and trichoscopic images were analyzed, and the improvement in the scale and the vascular component of patients treated with oral isotretinoin was described.
A total of 132 patients were included. The most frequent trichoscopic findings were perifollicular scale, peripilar desquamation, and interfollicular scale. Most of the 7 patients treated with oral isotretinoin showed a partial improvement in the scale and the vascular component.
The peripilar scale resembling the outer skin of an onion bulb could be used as a marker for this disease. We observed partial response to oral isotretinoin, probably due to the chronic character of this condition secondary to continuous release of formaldehyde, suboptimal doses, or a short treatment time.
湿疹样银屑病样皮炎被描述为巴西角蛋白治疗后的一种并发症，毛囊周围鳞屑的存在类似于洋葱鳞茎的外层皮肤，这被报道为一种特征性的皮肤镜表现。迄今为止，尚未有针对这种病症的治疗方法被报道。
对诊断为湿疹样银屑病样皮炎的患者进行了一项回顾性研究。分析了临床和皮肤镜图像，并描述了口服异维A酸治疗患者鳞屑和血管成分的改善情况。
共纳入132例患者。最常见的皮肤镜表现为毛囊周围鳞屑、毛发周围脱屑和毛囊间鳞屑。7例接受口服异维A酸治疗的患者中，大多数患者的鳞屑和血管成分有部分改善。
类似于洋葱鳞茎外层皮肤的毛发周围鳞屑可作为这种疾病的一个标志物。我们观察到口服异维A酸有部分反应，这可能是由于甲醛持续释放导致这种病症具有慢性特征、剂量不足或治疗时间短所致。
