A 27-year-old Chinese man presented with a nonpruritic rash on his thumbs that had developed gradually over a 1.5-year period (Figure 1). Similar lesions subsequently appeared on the antecubital fossae, knees (Figure 2), and popliteal fossae. The lesions were persistent and nonmigratory and were apparently aggravated by heat and sweating. The patient had a younger brother, who was similarly affected. His medical history was otherwise unremarkable.
