Abstract
Tinea nigra, a superficial fungal infection caused by Phaeoannellomyces werneckii, presents as a hyperpigmented, nonscaling macule of variable size and shape. Typically lacking induration, erythema, or pruritus, these "ink spot" lesions may resemble junctional nevi or malignant melanoma. Rapid, noninvasive diagnosis can be provided by potassium hydroxide examination, demonstrating numerous large, dematiaceous hyphae.
摘要
黑癣是由威尼克菲奥暗色孢霉引起的一种浅表真菌感染，表现为大小和形状各异的色素沉着、无鳞屑斑。这些“墨渍斑”损害通常无硬结、红斑或瘙痒，可能类似交界痣或恶性黑色素瘤。通过氢氧化钾检查可进行快速、非侵入性诊断，显示大量粗大的暗色菌丝。
