汗孔角化病

While porokeratosis is practically asymptomatic,unusual pruritic variant has been reported and designated as "eruptive pruritic papular porokeratosis" or "inflammatory stage of DSP".

本病一般无临床症状，但伴明显瘙痒的汗孔角化症已经有文献报告，并被命名为&发疹性瘙痒性丘疹型汗管角化症&或&处于炎症反应期的DSP&。

We recently encountered three old men with pruritic porokeratosis .We propose the term "eruptive pruritic papular porokeratosis" for describing this unusual variant of porokeratosis.

笔者近期诊断三例这样的病患并推荐使用&发疹性瘙痒性丘疹型汗管角化症&来命名这一特殊类型的汗孔角化症。
