A 1-month-old Hispanic boy, who had been carried to term during a pregnancy without complications, was referred for evaluation of a reddish growth that he had had on his left calf since birth. During the second week of life, the lesion spontaneously ulcerated and crusted. Approximately 1 week later, the parents noted that the lesion had become slightly smaller. There was no family history of similar lesions.
On physical examination, there was a 1-cm firm, nontender, red-brown, crusted, crateriform nodule on the posterior aspect of the left calf (Figure 1). The lesion was freely mobile and did not urticate on firm stroking. There was no organomegaly or lymphadenopathy, and the findings of the rest of the physical examination were unremarkable.
