Subungual malignant melanoma developed on both great toes of a 61-year-old woman. The lesions had been diagnosed elsewhere as ingrowing toenails and had been treated as such for two years. The difficulty in clinical diagnosis is illustrated by the description of three other patients with subungual malignant melanoma. The tumour should be considered as a possible cause of any persistent abnormality of the nail bed or the nail itself, especially if it is pigmented.
一名61岁女性的双侧大脚趾均出现了甲下恶性黑色素瘤。这些病变在其他地方被诊断为嵌甲，并按此治疗了两年。另外三名甲下恶性黑色素瘤患者的描述说明了临床诊断的困难。该肿瘤应被视为甲床或指甲本身任何持续性异常的可能原因，尤其是有色素沉着时。
