摘要

A 1-year-old boy presented with a solitary alopecic atrophic area on the scalp and a history of a fluid-filled lesion at the site that had presented a few days after birth and healed with thinning of skin (Figure 1A). Examination revealed a 2 × 2 cm solitary, well-defined alopecic patch with atrophy on the scalp vertex without any underlying bone defect.
