A 4-year-old white boy presented with a 3-year history of hair loss. The area of hair loss had not changed significantly since it was first noticed. The area had been treated unsuccessfully with intralesional triamcinolone and topical clobetasol ointment.
Physical examination revealed an oval 3 × 4-cm patch of nonscarring alopecia on the anterior aspect of the left side of the scalp (Figure 1). On closer examination, fine vellus hairs and a few terminal hairs could be seen. A punch biopsy specimen was obtained from the area of hair loss (Figure 2 and Figure 3).
