A sixty-one year old white female was referred to the Dermatology Department to treat an ingrown nail in the inner corner of the left hallux. Examination of the entire nail unit showed the presence of xanthonychia in the outer corner besides thickening and increase in the transverse curvature of the nail plate. Dermoscopy and nuclear magnetic resonance of the free edge of the nail plate detected characteristic signs of onychomatricoma, a diagnosis that was later confirmed by anatomopathological exam.
一名61岁的白人女性被转诊至皮肤科，以治疗左拇趾内角的嵌甲。对整个甲单位进行检查后发现，除了甲板增厚和横向弯曲增加外，外角还存在黄色甲。对甲板游离缘进行皮肤镜检查和核磁共振检查，发现了甲母质瘤的特征性体征，这一诊断后来通过解剖病理学检查得到证实。
