"Black heel" (calcaneal petechiae) is a traumatic lesion affecting the back or posterolateral aspect of the heel. It is seen almost exclusively in adolescentes or young adults engaged in active sports, notably basketball, but also football, lacrosse, tennis, and so forth. The lesion is disposed horizontally at the upper dege of the calcaneal fat-pad and consists of grouped punctate hemorrhages, the nature of which is revealed by repeated paring of the lesion. The nature of the pigment is shown by specialized stains. "Black heel" is probably more common than is realized. It is likely to be cuased by a shearing or pinching stress from abrupt contact of th foot with a floor or hard ground. As it si usually symptomless, it may be disregarded or only observed by chance. However, it has been confused clinically with a melaonoa, and as it is such a trivial self-healing process, it is important that it be recognized for what it is.
“黑踵”（跟骨瘀点）是一种累及足跟后部或后外侧的创伤性病变。几乎仅见于从事活跃运动的青少年或年轻人，尤其是篮球运动员，也可见于足球、长曲棍球、网球等运动的参与者。该病变位于跟骨脂肪垫上缘水平，由成群的点状出血组成，通过反复削除病变可揭示其本质。色素的性质通过特殊染色显示。“黑踵”可能比人们意识到的更为常见。它可能是由于足部与地板或硬地面突然接触产生的剪切或挤压应力所致。由于通常无症状，可能被忽视或仅偶然被发现。然而，临床上它曾与黑色素瘤混淆，鉴于其是一个如此轻微的自愈过程，重要的是要认清其本质。
