Irritated hyperhidrotic soles with multiple small pits are pathognomonic for pitted keratolysis (PK). Here we show the dermatoscopic view of typical pits that can ensure the diagnosis. PK is a plantar infection caused by Gram-positive bacteria, particularly Corynebacterium. Increases in skin surface pH, hyperhidrosis, and prolonged occlusion allow these bacteria to proliferate. The diagnosis is fundamentally clinical and treatment generally consists of a combination of hygienic measures, correcting plantar hyperhidrosis and topical antimicrobials.
伴有多个小坑的刺激性多汗足底是窝状角质松解症（PK）的特征性表现。在此我们展示典型小坑的皮肤镜视图，这有助于确诊。PK是一种由革兰氏阳性菌，尤其是棒状杆菌引起的足底感染。皮肤表面pH值升高、多汗症以及长时间的封闭状态会使这些细菌大量繁殖。诊断主要基于临床症状，治疗通常包括卫生措施、纠正足底多汗症以及局部使用抗菌药物。
