When evaluating pediatric patients with hyperpigmented lesions on the plantar aspect of the feet, the differential diagnosis should include talon noir, acral melanoma, and verruca with thrombosis. Talon noir are asymptomatic brown-black pigmented macules formed by intraepidermal hemorrhages of the feet caused by shear-force injury. Spontaneous resolution of talon noir typically occurs within 2–3 weeks. Clinicians should ensure that their patients who participate in sports have appropriately fitting shoes, which may prevent these lesions from occurring. This case report highlights a unique case of talon noir occurring in a young baseball player with an atypical distribution of plantar macules.

在评估足底色素沉着过度病变的儿科患者时，鉴别诊断应包括黑爪、肢端黑色素瘤和伴有血栓形成的疣。Talon noir 是由剪切力损伤引起的足部表皮内出血形成的无症状棕黑色色素斑。Talon noir 的自发消退通常在 2-3 周内发生。临床医生应确保参加运动的患者穿着合适的鞋子，以防止这些病变的发生。本病例报告强调了一个独特的黑爪病例，该病例发生在一名具有非典型足底斑疹分布的年轻棒球运动员身上。
