A 2-day-old boy, the second child of healthy, nonconsanguineous parents, who had been normally delivered at the 42nd week of an uneventful pregnancy was referred to our dermatologic department for the evaluation of a congenital, nontender hemispheric tumor that was 2 cm in diameter. This lesion, which was localized in the right deltoid muscle, had a smooth surface that was pink-red with some tiny telangiectasias and surrounded by a 4- to 5-mm, raised, pale halo (Figure 1).
