A 22-year-old black male patient developed discrete, exquisitely painful bilateral plantar lesions. Histologic examination revealed a cutaneous groove filled by a keratin plug (cornoid lamella). There is focal absence of granular layer underlying this defect. The differential diagnosis of this lesion, familiar to podiatrists but relatively unknown to dermatologists, is discussed.
一名22岁的黑人男性患者双侧足底出现散在的、剧痛性损害。组织学检查显示一条被角质栓（鸡眼样板层）填充的皮肤沟。该缺损下方的颗粒层局部缺失。本文讨论了这种损害的鉴别诊断，足病医生对此熟悉，但皮肤科医生相对不了解。
