A 16-year-old boy presented with a number of asymptomatic pigmented macules on the volar aspect of his index fingers. Dermoscopy of each macule revealed a parallel ridge pattern of homogenous reddish-brown pigment. We propose that these lesions were induced by repetitive trauma from a Sony PlayStation 3 (Sony Corporation, Tokyo, Japan) vibration feedback controller. The lesions completely resolved following abstinence from gaming over a number of weeks. Although the parallel ridge pattern is typically the hallmark for early acral lentiginous melanoma, it may be observed in a limited number of benign entities, including subcorneal haematoma.
一位 16 岁男孩出现多个无症状的色素斑，位于食指的掌侧面。每个斑块的皮肤镜检查显示均匀的红棕色色素呈平行脊状图案。我们推测这些病变是由索尼 PlayStation 3（索尼公司，东京，日本）振动反馈控制器反复的创伤引起的。经过数周的戒断游戏后，病变完全消退。虽然平行脊状模式通常是早期肢端雀斑样黑素瘤的特征，但它也可能在少数良性实体中观察到，包括皮下血肿。
