An early and accurate diagnosis is critical for the optimal management of subungual melanoma; the absence of Hutchinson's nail sign makes an accurate diagnosis extremely difficult. Previous publications show that most subungual melanomas have Hutchinson's nail sign. In this report, we present a rare case of a subungual melanoma without Hutchinson's nail sign and discuss the importance of cautious evaluations of Hutchinson's nail sign by dermoscopy.
