An otherwise healthy 18-year-old Hispanic man was evaluated for a scalp lesion that had been present since birth. The lesion was initially reported to be an asymptomatic, skin-colored, dome-shaped nodule with a slightly irregular surface. When the patient was 16 years old, it had gradually begun to elevate and enlarge. Alopecia also occurred. The lesion was nonpruritic and nontender and showed limited mobility. There was no history of trauma or chronic irritation at the site of the lesion. The patient had no significant medical history. His family history revealed no genetic diseases, and a review of systems revealed no abnormalities.
