REPORT OF A CASE
A male infant born to a healthy 26-year-old mother was noted at birth to have a mass on the posterior aspect of his left upper arm. The lesion was a brown-red, firm, well-defined nodule that measured 1.5 × 1.3 cm in diameter and was apparently nontender. The mass had a central yellow crust but was not fixed to underlying muscle (Fig 1). No other masses were seen. The results of the remainder of the neonatal examination were unremarkable. There
