Abstract：
UNASSIGNED: The Spitz nevus (SN) is an acquired melanocytic neoplasm composed of epithelioid and/or spindle cells, which tends to develop in childhood. In pediatric patients, it is usually located on the face and neck. Unusual locations have been found in the literature, such as the penis, mouth, and tongue, as well as 2 cases of ungual SN.
UNASSIGNED: A 15-year-old male evaluated for dark brown-black longitudinal melanonychia that covered 40% of the nail, with pseudo-Hutchinson\'s sign, of 1 year of evolution.
UNASSIGNED: The SN accounts for 1% of the melanocytic neoplasms. In the present paper, we show the third case of ungual SN never previously disclosed, which presents a zigzag pattern reported in the literature for its association with the pediatric population.

摘要：
■Spitz痣（SN）是一种获得性黑素细胞肿瘤，由上皮样和/或梭形细胞组成，这往往在童年发展。在儿科患者中，它通常位于面部和颈部。在文献中发现了不寻常的位置，比如阴茎，嘴，还有舌头,以及2例指甲SN。
■一名15岁的男性被评估为深棕黑色纵向黑甲，覆盖了40％的指甲，用伪哈钦森的标志,一年的进化。
■SN占黑色素细胞肿瘤的1%。在本论文中，我们展示了第三例以前从未披露过的ungaalSN，它呈现了文献中报道的锯齿形模式，因为它与儿科人群有关。
