pruritic

Prurigo nodularis （PN） is a chronic pruritic dermatosis of unknown etiology, characterized by firm, symmetrically localized hyperkeratotic pruritic papules and nodules.

结节性痒疹为一因未明慢性瘙痒性发疹性皮肤。点为突出于皮面角化过度丘疹、结节，烈瘙痒，呈对称性分布。

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

笔者近期诊断三例患并推荐使用“发疹性瘙痒性丘疹型汗管角化症”来命名一殊类型汗孔角化症。
