A 5-month-old Hispanic boy, who had been carried to term during a pregnancy without complications, was referred for evaluation of an asymptomatic plaque on the right wrist that had first been noticed at the age of 2 months. The lesion was initially soft but later became firmer and larger. There was no family history of similar skin lesions. The child was otherwise healthy.
On physical examination, there was a dull-red, firm, noncompressible, nontender nodule measuring 2 × 3 cm in diameter over the flexor aspect of the right wrist. Deep skin creases were seen within the surface of the nodule, and it appeared fixed to the underlying tissue (Figure 1). No other masses were seen. The findings of the rest of the physical examination were unremarkable.
