Adam Taintor, MD


November 02, 2011

History and Clinical Presentation

A 9 year-old boy presents with a scalp lesion that he has had for 2 years.


This otherwise healthy white patient has had an asymptomatic scalp lesion on his scalp for 2 years. The child has a history of gross motor delay and low muscle tone, both of which have since resolved. He is an average student in the third grade. The patient's family has no history of genetic syndromes.

Physical Examination

On examination, the patient appeared to be in excellent general health. A 3- to 4-mm pink papule is seen on the right occipital scalp (Figure 1).

The patient is also noted to have mild frontal bossing and macrocephaly. A biopsy of the scalp lesion was performed.

A month later, the patient returned to the clinic with a second pink papule on the scalp. A biopsy showed histology similar to that of the first lesion.
