We recently saw a young Chinese weight lifter who noted an asymptomatic petechial eruption over the volar aspects of his fingers; this eruption was identical to the petechial lesions seen in "black heel."
Report of a Case
An 18-year-old Chinese weight lifter who had not lifted weights for several months, noted considerable sliding and friction over the bar as he gripped and lifted the weights. The next day, he saw speckled, rust-red to black, linear, nonprurutic petechial lesions over the volar aspects of his fingers, corresponding to the points where his grip was strongest (Figure). Such an eruption is apparently a well-known occurrence among weight lifters, particularly in novices.
